Vinyl-disulfide-chelating ligand

A final example Illustrates the versatility that transition metal sulfur systems may provide. An activated acetylene has been shown(68 ) to Insert Into a metal-sulfur bond In Mo202S2(S2)2 forming a vinyl disulfide chelating ligand. 

The versatility of transition-metal sulfur systems is further illustrated by the observation that activated acetylene can insert into a metal-sulfur bond in Mo202S2(S2)2 , forming a vinyl-disulfide-chelating ligand...
