Unusual PC Bond Cleavage by Double Dichlorosilylene Transfer from Trichlorosilyltrimethylgermane to P-Phosphanyl Phosphaalkenes

Abstract

Silicon implants for double bonds: An unusual tetrasilymethane derivative, the 2-phospha-1,3-disiletane 2 is formed through the spontaneous consecutive addition of two equivalents of SiCl2 to the phosphaalkene 1. Simultaneously the diphosphene 3 is also formed, which contains a central PP bond and silylphosphane groups.
