A new discrete supramol. metallacage functionalized with an alkynylplatinum(II) 2,6-bis(benzimidazole-2′-yl)-pyridine (bzimpy) moiety has been successfully constructed via coordination-driven self-assembly. A study on the hierarchical self-assembly behavior of the obtained metallacage revealed that it displayed a solvent-induced emission switch accompanied by enhancement of the emission intensity as a result of the change in intermol. Pt···Pt and π-π interactions. More interestingly, the metallacage has been found to spontaneously self-assemble into a transparent metallogel at room temperature without a heating-cooling process.

A proof-of-concept example of catalytic regioselective cage B(8)-H functionalization of o-carboranes was disclosed for the 1st time. Under the help of an acylamino directing group at cage B(3), B(8)-arylated, B(4,7,8)-triarylated and B(4,7,8)-trifluorinated o-carborane derivatives were conveniently prepared From isolation of a key intermediate, D labeling experiments and DFT calculations, a reaction mechanism involving a high-valent Pd induced cage-walking from B(4) to B(8) vertex is proposed to account for the regioselective B(8)-H activation.

Li, Ming published the artcileCooperative Strategy for the Highly Selective Intermolecular Oxycarbonylation Reaction of Alkenes using Palladium Catalyst, Category: nitriles-buliding-blocks, the publication is Angewandte Chemie, International Edition (2016), 55(44), 13843-13848, database is CAplus and MEDLINE.

A novel method for intermol. functionalization of terminal and internal alkenes has been designed. The electrophilic reagent, hypervalent iodine, plays a key role in this process by activating the alkene C=C bond for nucleophilic addition of the palladium catalyst. This process generates an iodonium-containing palladium species which undergoes CO insertion. The new approach, intermol. oxycarbonylaton reactions of alkenes, has been achieved and carried out under mild reaction conditions to produce the corresponding β-oxycarboxylic acids with excellent efficiencies and levels of regio- and diastereoselectivity. Thus, e.g., treatment of 5-phthalimido-1-pentene with Pd(OAc)₂, PhI(OAc)₂, BF₃.Et₂O and CO in toluene/MeCN afforded I (95%, regioselectivity > 20:1).

Yang, Weibo published the artcileOrchestrated Triple C-H Activation Reactions Using Two Directing Groups: Rapid Assembly of Complex Pyrazoles, Safety of Tetrakis(acetonitrile)palladium(II) Ditriflate, the publication is Angewandte Chemie, International Edition (2015), 54(8), 2501-2504, database is CAplus and MEDLINE.

A sequential triple C-H activation reaction directed by a pyrazole and an amide group leads to the well-controlled construction of sterically congested dihydrobenzo[e]indazole derivs I [R¹ = H, 4-Me, 3-Me, 3,4-diMe, 4-Ph, 4-F, etc.; R² = Me, (CH₂)₂Ph, (CH₂)₃Ph; R³ = Me, Et, iBu, cyclohexylmethyl; R²R³=(CH₂)₅; R⁴ = Me, Et]. This cascade reaction demonstrates that the often problematic competing C-H activation pathways in the presence of multiple directing groups can be harvested by design to improve step economy in synthesis. Pyrazole as a relatively weak coordinating group is shown to direct Csp³-H activation for the first time.

Sakata, Yoko published the artcileMetallonanobelt: A Kinetically Stable Shape-Persistent Molecular Belt Prepared by Reversible Self-Assembly Processes, Computed Properties of 68569-14-2, the publication is Inorganic Chemistry (2018), 57(24), 15500-15506, database is CAplus and MEDLINE.

A triptycene-based shape-persistent belt-shaped macrocycle, metallonanobelt, was synthesized by the self-assembly of 2,3,6,7-tetraaminotriptycene L and square planar Pd²⁺. The pentamer was selectively formed by the complexation of L with Pd²⁺ in the presence of the pillar[6]arene derivative P6 having triethylene glycol pendant as a template, whereas a mixture of a trimer, tetramer, and pentamer was obtained in the absence of the template. The pentamer was successfully isolated based on the solubility difference between the metallonanobelt and the template. Also the isolated pentamer was remarkably stable in solutions such as acetonitrile or methanol thanks to the relatively inert planar chelate metal complex, [Pd(o-phenylenediamine)₂] unit. Thus, the authors can handle the metallonanobelt almost as a static organic nanobelt that was synthesized covalently.

Wang, Mei-Ling published the artcileMizoroki-Heck Reaction of Unstrained Aryl Ketones via Ligand-Promoted C-C Bond Olefination, COA of Formula: C10H12F6N4O6PdS2, the publication is Organic Letters (2021), 23(6), 2147-2152, database is CAplus and MEDLINE.

Mizoroki-Heck reaction of unstrained aryl ketone with acrylate/styrene was accomplished via palladium-catalyzed ligand-promoted C-C bond cleavage. Various (hetero)aryl ketones were compatible in the reaction, affording the alkene product in good to excellent yields. Further applications in the late-stage olefination of some drugs, natural products, and fragrance-derived aryl ketones demonstrated the synthetic utility of this protocol. By employing ketone as both the directing group and the leaving group, 1,2-bifunctionalization was achieved via sequential ortho-C-H alkylation/ipso-Heck olefination.

Sau, Abhijit published the artcilePalladium-Catalyzed Direct Stereoselective Synthesis of Deoxyglycosides from Glycals, HPLC of Formula: 68569-14-2, the publication is Angewandte Chemie, International Edition (2017), 56(13), 3640-3644, database is CAplus and MEDLINE.

Palladium(II) in combination with a monodentate phosphine ligand enables the unprecedented direct and α-stereoselective catalytic synthesis of deoxyglycosides from glycals. Initial mechanistic studies suggest that in the presence of N-phenyl-2-(di-tert-butylphosphino)pyrrole as the ligand, the reaction proceeds via an alkoxy palladium intermediate that increases the proton acidity and oxygen nucleophilicity of the alc. The method is demonstrated with a wide range of glycal donors and acceptors, including substrates bearing alkene functionalities.

Yan, Xuzhou published the artcileEndo- and Exo-Functionalized Tetraphenylethylene M₁₂L₂₄ Nanospheres: Fluorescence Emission inside a Confined Space, Related Products of nitriles-buliding-blocks, the publication is Journal of the American Chemical Society (2019), 141(24), 9673-9679, database is CAplus and MEDLINE.

The intrinsic relationship between the properties of green fluorescent protein (GFP) and its encapsulated small mol. light machine has spurred many biomimicking studies, aiming at revealing the detailed mechanism and further promoting its wide applications in different disciplines. However, how to build a similar confined microenvironment to mimic the cavity of a β-barrel and the fluorescence turn-on process is a fundamental challenge for both chemists and biologists. Herein, two distinct exo- and endo-functionalized tetraphenylethylene (TPE)-based M₁₂L₂₄ nanospheres with precise distribution of anchored TPE moieties and unique photophys. properties were constructed by means of a coordination-driven self-assembly strategy. Under dilute conditions, the nanospheres fluoresce more strongly than the corresponding TPE subcomponents. Meanwhile, the endo-functionalized sphere is able to induce a higher local concentration and more restrained motion of the enclosed 24 TPE units compared with exo-functionalized counterpart and thus induces much stronger emission due to the restriction of the rotation of the pendant TPE units. The biomimetic methodol. developed here represents a promising way to understand and construct artificial GFP materials on the platforms of supramol. coordination complexes.

Chan, Kelvin S. L. published the artcileLigand-enabled cross-coupling of C(sp³)-H bonds with arylboron reagents via Pd(II)/Pd(0) catalysis, Safety of Tetrakis(acetonitrile)palladium(II) Ditriflate, the publication is Nature Chemistry (2014), 6(2), 146-150, database is CAplus and MEDLINE.

There have been numerous developments in C-H activation reactions in the past decade. Attracted by the ability to functionalize mols. directly at ostensibly unreactive C-H bonds, chemists have discovered reaction conditions that enable reactions of C(sp²)-H and C(sp³)-H bonds with a variety of coupling partners. Despite these advances, the development of suitable ligands that enable catalytic C(sp³)-H bond functionalization remains a significant challenge. Herein we report the discovery of a mono-N-protected amino acid ligand that enables Pd(II)-catalyzed coupling of γ-C(sp³)-H bonds in triflyl-protected amines with arylboron reagents. Remarkably, no background reaction was observed in the absence of ligand. A variety of amine substrates and arylboron reagents were cross-coupled using this method. Arylation of optically active substrates derived from amino acids also provides a potential route for preparing non-proteinogenic amino acids.
