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.
