Abstract

Reaction of 1.1. 2.2-tetrachlorodimethyldisilane (4) with 1.4-diazadienes like benzildianil (1), benzildi-p-tolil (2) and benzildi-p-anisil (3) leads to a 1.4-addition product of the disilane under cleavage of the Si Si bond (1a, 2a, 3a). The structure of 2a was determined by X-ray crystallography (crystal data: monoclinic, P2 tn, a= 14.661 (4), b= 12.283 (2), c= 17.564 (5) A ̊, β= 103.13°, Z= 4, R= 0.0585 for 5992 independent reflections). Surprisingly, 2a was ...
