Selenium‐Substituted Phosphaalkenes Obtained through 1,2‐Elimination of Chlorosilanes from Selenenylchlorophosphines
Abstract
Stable selenenyl‐chlorophosphines, bearing a silylalkyl group, were synthesized. Subsequent treatment with Lewis acids such as AlCl3 afforded the corresponding phosphaalkenes. A reaction mechanism that proceeds through an intramolecular 1,2‐elimination of chlorosilane was proposed.
Abstract
Stable selenenyl‐chlorophosphines, bearing a trisilylalkyl group, were synthesized, and their treatment with Lewis acids such as AlCl3 afforded the corresponding phosphaalkenes. The experimental results and theoretical calculations suggested that the reaction proceeds through the intramolecular 1,2‐elimination of chlorosilanes
