Alkyl groups migration from tetra-alkyl-silanes, -germanes, and -stannanes to carbenium ions, effected by Lewis acids: a novel method for synthesising hydrocarbons with a quaternary carbon atom
Abstract
Hydrocarbons with a quaternary carbon atom have been obtained by alkyl group transfer from group 4 tetra-alkyl derivatives to tertiary carbenium ions in the presence of Lewis acids.
