Dissociative electron attachment of para-substituted diphenylmethanols

摘要

Dissociative electron attachemt is a reaction in which a bond cleavage occurs irrevearsibly upon capturing solvated electron (e_s~-) Despite of various works on the subject, it is still not clear wheteher elecron attachment is concerted with the bond cleavage or not. We report here that dissociative electron attachment of p-substituted diphenyl-mentanols (Ae_2CHOH, Ar chemical bounds p-X-C_6H_4) giving the p-substituted diphenylmentyl radicals (Ar_2CH) and OH during pulse radiolyses of Ar_2CHOH in argonsaturated N,N-dimethylformamide (DMF) at room temperature.
