Highly selective synthesis of novel (E)-styrylsilatranes via ruthenium-catalyzed trans-silylation

Abstract

Protocols for the synthesis of cage-substituted 1-vinylsilatranes have been developed and updated. The 1-vinylsilatranes with organic substituents attached to silatrane cage were functionalized in ruthenium-catalyzed trans-silylation with olefins, leading to novel styrylsilatranes in high yields.
