Iron group metallocenes Cp2M (Cp = C5H5, M = Fe, Ru, Os) and chlorocarbon solvents RCl (CCl4, CHCl3, CH2Cl2, C2Cl4) form electron donor-acceptor (EDA) complexes.

Abstract
Iron group metallocenes Cp2M (Cp = C5H5, M = Fe, Ru, Os) and chlorocarbon solvents RCl (CCl4, CHCl3, CH2Cl2, C2Cl4) form electron donor-acceptor (EDA) complexes. During irradiation of EDA complexes in the presence of spin traps, nitroxide radical adducts of chlorocarbon radicals ·R have been detected, and on this basis a mechanism for the photolysis of EDA complexes is suggested. The ability of metallocenes, particularly Cp2Fe, to trap transient radicals ·R in electron transfer processes has been demonstrated. © 1989.File in questo prodotto:
