Silacyclohexadiene 6 was the desired precursor of silatoluene 2 as it was hoped that this system would undergo thermally induced 1, 3-migration of the trimethylsilyl group to afford conjugated diene 7 followed by 8 elimination of trimethylmethoxysilane. Precedent for 1, 3- sigmatropic migration of silicon on an all-carbon framework is found in the work of K~ art.~ Precedent for silene generation via thermal p elimination of Me3SiOMe from a Me3Si- ...
