A copper(I)-catalyzed bis-esterification of cyclic anhydrides with aryl and vinyl alkoxysilanes is described, in which the alkoxy and aryl (or vinyl) esters of dicarboxylic acids were prepared in one pot with moderate to good yields. Notably, vinyl trimethoxysilanes also worked well with this procedure.
