Preparation of Thiocarbonyl and Selenocarbonyl Complexes

Thiocarbonyl and selenocarbonyl metal complexes are generally prepared from carbon disulfide, CS2 thiophosgene, CSCI2 and carbon diselenide, CSc2, as well as from transition metal complexes such as metal carbonyls. Commonly, triphenyl-phosphine is utilized to eliminate sulfur or selenium  

Thiophosgene is used in reactions involving anionic complexes  

With some complexes, particularly those of platinum group metals, thiophosgene may undergo oxidative addition reaction
