INSERTION OF DIMETHYLSILYLENE INTO O-H AND N-H SINGLE BONDS

Article abstract of DOI:10.1016/S0022-328X(00)94358-4

Dimethylsilylene, generated by photolysis of dodecamethylcyclohexasilane, inserts efficiently into O-H single bonds of alcohols to yield alkoxydimethyl-silanes.Use of ethanol-O-d₁ yields ethoxydimethylsilane-Si-d₁.Dimethylsilylene also inserts into O-H single bonds of water or D2O to yield respectively tetramethyldisiloxane or tetramethyldisiloxane-Si2-d₂.Dimethylsilylene also inserts into N-H bonds of primary and secondary amines to yield aminodimethylsilanes.This reaction provides an efficient route to difunctional silanes.
