Abstract

Abstract To prove for a thermally-induced 1, 3-migration of silicon from silicon to produce a silicon—carbon double bond, 1, 2-divinyl-1, 1, 2, 2-tetramethyldisilane was pyrolyzed in a nitrogen-flow system at 620 C. All cyclic products can be rationalized as arising from an initial 1, 3-migration to form the intermediate silene, 2, 5-disila-2, 5, 5-trimethyl-2, 6- heptadiene. The major product. 1, 1, 3, 3-tetramethyl-1, 3-disilacyclobutane, is shown to ...
