摘要

Photolysis of triphenylmethylphosphonic acid and its dimethyl ester in ethanol gave biphenyl and a product derived from dimethoxyphosphinyl(pheny1)carbene. ... Upon UV irradiation in alkaline aqueous solution, p-nitro- benzylphosphonic acid (1) underwent CP bond cleavage to give p-nitrotoluene and orthophosphate (quantum yield, Q) = 0.80).' This Photochemical C-PbondcleavageoccursonlY fully dissociated state. In acidic solution (1) is stable even ...
