Abstract

Upon UV-irradiation, various phosphine oxides of the general structure I were found to be fragmented readily into free radicals I′ and I″

Laser flash photolysis studies revealed that radicals of type I" with R2 and/or R3 being phenyl groups possess a strong absorption band with a maximum around 330 nm. ε335nm= 1.9×104 1/mol cm was estimated for diphenyl phosphonyl radicals (Ph2P = O).
