EVIDENCE FOR THE INTERMEDIACY OF 1,1-DIMETHYL-2-PHENYL-1-SILA-1,3-BUTADIENE IN THE PHOTOCHEMISTRY AND PYROLYSIS OF 1,1-DIMETHYL-2-PHENYL-1-SILA-2-CYCLOBUTENE

Photolysis of 1,1-dimethyl-2-phenyl-1-sila-2-cyclobutene (I) in methanol and methanol-O-d₁ yields dimethylmethoxy(1-phenyl-2-propenyl)silane and dimethylmethoxy(1-d₁-1-phenyl-2-propenyl)silane, respectively, as major products.These products may be formed by reaction of methanol or methanol-O-d₁ with 1,1-dimethyl-2-phenyl-1-sila-1,3-butadiene.Gas phase pyrolysis of I and acetone or formaldehyde have also been studied.
