Brief introduction of 484-47-9

Quality Control of 2,4,5-Triphenylimidazole. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2,4,5-Triphenylimidazole, is researched, Molecular C21H16N2, CAS is 484-47-9, about Evidence for the Formation of 1,2-Dioxetane as a High-Energy Intermediate and Possible Chemiexcitation Pathways in the Chemiluminescence of Lophine Peroxides. Author is Boaro, Andreia; Reis, Roberta Albino; Silva, Carolina Santana; Melo, Diego Ulysses; Pinto, Alexander Garreta Goncalves Costa; Bartoloni, Fernando Heering.

A kinetic study of the chemiluminescent (CL) reaction mechanism of lophine-derived hydroperoxides and silyl peroxides induced by a base and fluoride, resp., provided evidence for the formation of a 1,2-dioxetane as a high-energy intermediate (HEI) of this CL transformation. This was postulated using a linear Hammett relationship, consistent with the formation of neg. charge on the transition state of HEI generation (ρ > 1). The decomposition of this HEI leads to chemiexcitation with overall low singlet excited state formation quantum yield (ΦS from 1.1 to 14.5 x 10-5 E mol-1); nonetheless, ΦS = 1.20 x 10-3 E mol-1 was observed with both peroxides substituted with bromine. The use of electron-donating substituents increases chemiexcitation efficiency, while it also reduces the rate for both formation and decomposition of the HEI. Different possible pathways for HEI decomposition and chemiexcitation are discussed in light of literature data from the perspective of the substituent effect. This system could be explored in the future for anal. and labeling purposes or for biol. oxidation through chemiexcitation.

Author is Adhikary, Saswati; Majumder, Leena; Pakrashy, Sourav; Srinath, Ravuri; Mukherjee, Kaustuv; Mandal, Chitra; Banerji, Biswadip.

An iodine-catalyzed, environmentally benign one-pot methodol. has been developed for the synthesis of diverse substituted imidazoles. This transition-metal-free, aerobic, water-mediated cyclization reaction is operationally simple and works well with different amines or aldehydes by multiple C-N bond formations with satisfactory yield. The methodol. is regioselective as well as scalable. These imidazole derivatives show excellent fluorescence properties both in the solid and solution phase, which is further extended to live-cell imaging. Due to the suitable fluorescence properties of these scaffolds, lysosome-directing groups are incorporated in two of these derivatized imidazoles to track intracellular lysosomes. Successfully, those mols. show bright blue fluorescence while detecting lysosomes in human or murine cells and can be considered to be rapid lysosome-staining probes.
