Motornov, Vladimir published the artcileCopper(I)-Catalyzed Regioselective Chan-Lam N2-Vinylation of 1,2,3-Triazoles and Tetrazoles, Formula: C30H24BrCuN2P, the publication is Advanced Synthesis & Catalysis (2019), 361(14), 3306-3311, database is CAplus.
Copper-catalyzed coupling of π-deficient NH-azoles with vinylboronic acids or vinyltrifluoroborate salt provided a direct route to N2-vinyl-1,2,3-triazoles and N2-vinyltetrazoles. The coupling reaction was efficiently catalyzed by (phen)Cu(PPh3)Br with low catalyst loading (5 mol%) under base-free conditions. The method was applicable for vinylation of unsubstituted, monosubstituted and disubstituted 1,2,3-triazoles with various functionalities with high N2-selectivity.
Advanced Synthesis & Catalysis published new progress about 25753-84-8. 25753-84-8 belongs to bromides-buliding-blocks, auxiliary class Copper, name is Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I), and the molecular formula is C30H24BrCuN2P, Formula: C30H24BrCuN2P.
