Cleavage of alkylsilanes by strong acids

Add time:08/01/2019    Source:sciencedirect.com

The stepwise cleavage of alkyl groups from (bromomethyl)trimethylsilane and (iodomethyl)trimethylsilane by fluorosulfonic acid has been studied with proton magnetic resonance. Exclusive methyl cleavage is observed in the first reaction of both compounds. The reaction of (bromomethyl)dimethylsilyl fluorosulfonate occurs with cleavage of both methyl and bromomethyl from silicon. The reaction of (iodomethyl)dimethylfluorosilane occurs with exclusive cleavage of the iodomethyl group.
