Irradiation of 7-(2,4,6-trialkylphenyl-)7-phosphanorbornene 7-oxides at 254 nm in the presence of alcohols or water led to H-phosphinic acid derivatives. The experimental data are consistent with the mechanism established earlier for P-phenyl derivatives, involving a five-coordinate adduct from the interaction of the phosphanorbornene and the protic species which then fragments. There is no evidence that the larger substituent allowed a competing reaction to occur where the first step is unimolecular fragmentation to a two-coordinate phosphoryl species.
