The results of u.v. irradiation of (Me3Si)3CSiPh2I in MeOH, n-C6H14, CCl4, Et2O, and PhOMe are interpreted in terms of the formation of cationic as well as free-radical organosilicon intermediates.

U.v. irradiation (medium-pressure Hg lamp) induces reaction of TsiSiPh2I (1a) 3Si)3C> with methanol to give both the unrearranged and rearranged methoxides TsiSiPh2OMe and (Me3Si)2C(SiPh2Me)(SiMe2OMe); in the presence of LiNO3 some (Me3Si)2C(SiPh2Me)(SiMe2ONO2) is also formed.The analogous solvolysis in PhNH2 gives the rearranged anilide (Me3Si)2C(SiPh2Me)(SiMe2NHPh).These reactions are thought to involve the intermediate formation of a silico-cation.On the other hand the exclusive formation of the unrearranged chloride TsiSiPh2Cl upon irradiation in CCl4 appears to involve a free-radical process.The photoinduced rearrangement of (1a) to (Me3Si)2C(SiPh2Me)(SiMe2I) in n-C5H12, n-C6H14, Et2O, and PhOMe may involve a cationic intermediate, but a free radical rearrangement cannot be ruled out; the subsequent formation of a disilaindane derivative (6) in PhOMe probably involves cyclization of a free radical.The iodide TsiSiPhMeI also undergoes rearrangement to (Me3Si)2C(SiPhMe2)(SiMe2I) upon irradiation in n-C5H12.The methanolysis of TsiSiMe2I is also photo-catalysed, though less effectively than that of (1a).
