摘要
We have studied 9-anthroic acid sensitized photolysis of dipbenyliodonius salts through fluorescence quenching, products analysis and Photo-CIDNP. The photoinduced electron transfer rate constant bas calculated to be 8.6×10 10/mol s. From photo-CIDNP study, both diphenyliodo and pbenyl radicals were confirmed as intermediates. Benzene is a cage escaped product from a singlet radical pair and diphenyliodonium Salt is a recombination preduct from a triplet radical pair.
