Si₃S-, Si₃Se-, Si₃Te-Bicyclo[1.1.0]butanes and Si₃S₂-Bicyclo[1.1.1]pentane

Abstract

The reaction of trisilirene 1 with propylene sulfide or elemental sulfur produced Si₃S-bicyclo[1.1.0]butane 2, which underwent Si–Si insertion of a second S atom forming Si₃S₂-bicyclo[1.1.1]pentane 3. Analogous reactions of 1 with elemental Se or Te resulted in the formation of heavier analogues of 2, namely, Si₃Se-bicyclo[1.1.0]butane 4 and Si₃Te-bicyclo[1.1.0]butane 5.
