SYNTHESIS, STRUCTURE, AND REACTIONS OF THIOCARBONIC ACID DERIVATIVES NEW PENTATHIODIPERCARBONATES, (RSS)2C=S, α,α,α-TRIS(DISULFIDES), AND THE FIRST α,α,α-TRIS(TRISULFIDE)

Novel bis(perhaloalkyl) pentathiodipercarbonates 5b-d have been synthesised by reaction of sulfenyl chlorides with metal trithiocarbonates, and the heptathio analog 21a was prepared similarly.Lenthionine 19 is the main product when diiodomethane is treated with sodium tetrathiopercarbonate.A rearrangement of bis(alkyltrithio)dichloromethanes 24 has been observed.Additions of sulfenyl chlorides and of thiosulfenyl chlorides to the thiocarbonyl compounds 5 and 21a were achieved in acetonitrile.The structures of the first crystalline pentathiodipercarbonate 5a and α,α,α-tris(disulfide) 29a, and of the first reported α,α,α-tris(trisulfide) 31a have been determined by X-ray crystallography.
