Zhou, Jianwei published the artcileESR studies of the photolysis of (Ph3P)3CunXn and (Ph3P)(biL)CuX, Application In Synthesis of 25753-84-8, the publication is Huaxue Xuebao (1987), 45(1), 74-6, database is CAplus.
Active radicals in the photolysis of (Ph3P)3CunXn (n = 1, 2; X = Cl, Br, I, CN) and (Ph3P)(biL)CuX (X = Cl, Br, I; biL = 2,2′-dipyridyl, 1,10-phenanthroline) were investigated by combination of spin trapping technique, chromatog. and ESR spectroscopy. The formation of free radicals Ph. and Ph2P. was confirmed by the hyperfine structure of the ESR spectra of the spin adducts formed between Ph. or Ph2P. and phenyl-tert-butylnitrone.
Huaxue Xuebao 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 C7H13ClNNaO5S, Application In Synthesis of 25753-84-8.
