The photoreactions of tetraethylpyrophosphite, tetraphenylbiphosphine, diphenylphosphine oxide, and tetraethylbiphosphine disulphide with five quinones or quinonoid compounds have been studied by esr spectroscopy; P(O)Ph2 and P(O)(OEt)2 radicals add to both carbon- carbon and carbon-oxygen double bonds, whilst with Ph2P and P(S)Et2 radicals only the species resulting from addition to a carbonyl group are observed.It is also reported that the photogenerated quinone triplets react with tetraethylpyrophosphite leading to the formation of diethoxyphosphonyl radicals, which in turn add to other ground state quinone molecules, the diethoxyphosphinyl adduct to a carbonyl group being also formed in the process.

Arylsilyl radicals were found to add to a carbonyl oxygen of various p-quinones to produce siloxy-substituted phenoxyl radicals.Likewise the reaction of diphenylphosphino-radical with p-quinones produced similar phenoxyl radicals.For the unsymmetrical 2,6
