The photolysis of diazomethylenebis(diphenylphosphane oxide) (5), accessible by diazo group transfer reaction, in protic nucleophiles such as water, methanol, and piperidine yields the phosphinic acid 12a and its derivatives 10b and c.The carbene 9 and the phosphene 10 are intermediates of the reaction.The methyl phosphinate, isolated as mixture of the diastereomers 12b' and 12b" may be transfered into the phosphinic acid 12a via the silylester 13. - The photolysis of 5 in benzene in the presence of benzaldehyde takes an unusual way (formation of 6, 18, 20, 21, and of benzil); the benzoyl radical plays a key role in the interpretation of this reaction.
