ABSTRACT:
A process is provided for preparing unsaturated imidoalkoxysilane which comprises imidating substantially water-free Diels-Alder protected unsaturated N-substituted cyclic imide with aminosilane to provide Diels-Alder protected unsaturated imidoalkoxysilane without the use of chemical desiccants. The Diels-Alder protected unsaturated imidoalkoxysilane produced is then deprotected to provide unsaturated imidoalkoxysilane and the Diels-Alder protecting diene is regenerated to the process. A Diels-Alder intermediate is also provided.
