Abstract
A method for preparing a bis(alkoxysilylorgano)dicarboxylate includes reacting a haloorganoalkoxysilane, a dimetal salt of a dicarboxyl functional compound, and a phase transfer catalyst. A quaternary iminium compound of a polyaza, polycycloalkene is useful as the phase transfer catalyst. The product may be a bis(alkoxysilylalkyl)fumarate, which is useful as a coupling agent in rubber compositions for tire applications.
