The reaction of dimethoxymethylphenylsilane with Li metal in excess Me3SiCl in THF to produce the products the diastereomeric isomers of 2-[2,2-bis(trimethylsilyl)ethylidene]-1-methoxy-1-methyl-3,4,5-tris(trimethylsilyl)silolane, contracted from six- to five-membered rings, as well as the expected products dimethoxymethyl(Ttc)silane synthesized via a Birch-type reductive silylation[1]. Dimethoxymethylphenylsilane

Synthesis

Sodium metal particles suspension was added to a mixture of 62.5 g of chlorobenzene and 227 g of methyltrimethoxysilane, and then 0.32 g of 15-crown-5 was added. The reaction was carried out at 38 ° C for 2 h , The reaction was stopped, and the reaction mixture was filtered and vacuum-distilled to give Dimethoxymethylphenylsilane in a yield of 87%.
Dimethoxymethylphenylsilane
