Abstract

A method for producing a reaction product comprising an ester-functional silane, the method comprising: i) reacting a composition comprising: a) a haloorganosilane, b) a metal salt of a carboxy-functional compound, c) a phase transfer catalyst comprising a bicyclic amidine, an iminium compound, or a mixture thereof, provided that the iminium compound is not an acyclic guanidinium compound or pyridinium compound, and d) a co-catalyst, provided that the co-catalyst is optional when the phase transfer catalyst comprises the iminium compound.
