ESR studies of photolysis of (Ph3P)3 CunXn and (Ph3P) (biL) CuX

Abstract

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.

Key words: PYRIDINE P, REACTION MECHANISM, HALIDE, CATALYST, ELECTRON SPIN RESONANCE SPECTROMETRY, COPPER COMPLEX, COLUMN CHROMATOGRAPHY, TRIPHENYLPHOSPHINE, FREE RADICAL, PHOTODECOMPOSITION
