Photolysis of permethylated linear and branched-chain polysilanes

Abstract
Permethylated linear polysilanes Me[SiMe2]nMe (n= 3–6) and branched-chain polysilanes Me3Si[(Me3Si)SiMe]nSiMe3(n= 1,2) undergo photolysis at room temperature with loss of dimethylsilylene Me2Si: in the former case and (trimethylsilyl)methylsilylene Me3SiSiMe: in the latter.
