This manuscript describes the Ni-catalyzed coupling of azoles with aromatic nitriles. The use of BPh₃ promotes these arylations with electronically diverse azoles and benzonitriles. While the nickel catalyst is necessary for the arylations of Ph oxazoles, arylation of benzoxazoles with some nitriles affords the arylated products even in the absence of the Ni catalyst albeit in lower yield than the catalyzed process. The Ni-catalyzed process exhibits higher rates and a broader scope than the uncatalyzed transformation.

Reilly, Sean W. published the artcileLate-Stage Carbon Isotope Exchange of Aryl Nitriles through Ni-Catalyzed C-CN Bond Activation, Related Products of nitriles-buliding-blocks, the publication is Journal of the American Chemical Society (2021), 143(12), 4817-4823, database is CAplus and MEDLINE.

A facile one-pot strategy for ¹³CN and ¹⁴CN exchange with aryl, heteroaryl, and alkenyl nitriles using a Ni phosphine catalyst and BPh₃ is described. This late-stage carbon isotope exchange (CIE) strategy employs labeled Zn(CN)₂ to facilitate enrichment using the nonlabeled parent compound as the starting material, eliminating de novo synthesis for precursor development. A broad substrate scope encompassing multiple pharmaceuticals is disclosed, including the preparation of [¹⁴C] belzutifan to illustrate the exceptional functional group tolerance and utility of this labeling approach. Preliminary exptl. and computational studies suggest the Lewis acid BPh₃ is not critical for the oxidative addition step and instead plays a role in facilitating CN exchange on Ni. This CIE method dramatically reduces the synthetic steps and radioactive waste involved in preparation of ¹⁴C labeled tracers for clin. development.

Wang, Xueqiang published the artcileMetal-Free Etherification of Aryl Methyl Ether Derivatives by C-OMe Bond Cleavage, HPLC of Formula: 261951-87-5, the publication is Organic Letters (2018), 20(14), 4267-4272, database is CAplus and MEDLINE.

Alkoxyaryl (particularly methoxyaryl) nitriles such as 2-methoxybenzonitrile underwent chemoselective etherification (nucleophilic aromatic substitution) reactions with alcs. mediated by KOt-Bu or KHMDS in 1,4-dioxane to yield different alkoxyaryl nitriles. Primary, secondary, and tertiary alcs. were effective, and natural product or pharmaceutical-derived alcs. were used; the method was used to prepare butoxycaine in three steps from 4-methoxybenzonitrile. 4-Cyanophenyl (+)-menthyl ether was converted to a variety of derivatives by nitrile functionalization reactions. DFT calculations and exptl. results are consistent with potassium ion-mediated activation of the methoxy group through binding to the nitrile and support an S_NAr mechanism for the etherification reaction.

Natte, Kishore published the artcilePalladium-Catalyzed Trifluoromethylation of (Hetero)Arenes with CF₃Br, Formula: C9H6F3NO, the publication is Angewandte Chemie, International Edition (2016), 55(8), 2782-2786, database is CAplus and MEDLINE.

The CF₃ group is an omnipresent motif found in many pharmaceuticals, agrochems., catalysts, materials, and industrial chems. Despite well-established trifluoromethylation methodologies, the straightforward and selective introduction of such groups into (hetero)arenes using available and less expensive sources is still a major challenge. In this regard, the selective synthesis of various trifluoromethyl-substituted (hetero)arenes by palladium-catalyzed C-H functionalization is herein reported. This novel methodol. proceeds under comparably mild reaction conditions with good regio- and chemoselectivity. As examples, trifluoromethylations of biol. important mols., such as melatonin, theophylline, caffeine, and pentoxifylline, are showcased.
