✦ Synopsis

Treatment of hexakis(2,

tetrasilabuta-1,3-diene (1), R 2 Si=SiR±SiR=SiR 2 , with ammonia and chlorine furnishes the correspondingly substituted 1,4diaminotetrasilane (3) and 1,2,3,4-tetrachlorotetrasilane (6). While product 6 crystallizes as a racemate, 3 forms a con-glomerate of enantiomerically pure crystals. The change of colors during the formation of 6 indicates a stepwise reaction sequence.

The reaction of hexakis(2,4,6-triisopropylphenyl)tetrasilabuta-1,3-diene R 2 Si=SiR±SiR=SiR 2 (1) with atmospheric oxygen furnishes the oxidation product R 2 Si(O) 2 SiROSiR(O) 2 SiR 2 (5) by oxygen insertion into all Si±Si bonds. However, treatment of 1 with meta-chloroperoxobenzoic acid provides R
