Irradiation of cyclicenones 5–8 in the presence of Me3SiOP(OMe)2 or Me3SiOP(OEt)2 gives phosphonosilylation products of 1,4-conjugate addition which are hydrolyzed to the phosphonoketones 11–14 in 82–92% isolated yields. An SET process in which the triplet enone accepts an electron from the silyl phosphite is proposed to be the key initiation step in these reactions.
