was isolated from a mixture of 3,3′-dibromobithiophene, n-BuLi, and H2SiCl2 and was fully characterized. The reaction of DTSH2 with a Pt(0) complex, prepared in situ from [Pt(PCy3)2] and DPPE (1,2-bis(diphenylphosphino)ethane), produced a bis(silyl)platinum complex [Pt(DTSH)2(dppe)] (1) with two hydrodithienosilole ligands. DTSH2 undergoes cyclodimerization accompanied by skeletal rearrangement to afford
