The reaction between nickel carbonyl and thiophosgene (CSCI2) and the supposed polymeric carbon monosulphide of dewar)

The amorphous, brownish black substance obtained by Dewar and Jones from nickel carbonyl and thiophosgene, has not the composition (CS)x but contains organically combined chlorine. The reaction has been carried out in various solvents; the amorphous reaction products have been completely analysed and it appears that the solid adsorbs the solvent, which cannot be completely removed. The C: S ratio in these products therefore varies from 1: 0.8 to 1: 0.9. The reaction was also carried out in the vapour phase. The amorphous product so obtained also contained organically combined chlorine while the C:S ratio was 1: 1.03 in this case. Thus the product produced from nickel carbonyl and thiophosgene is not a polymeric form of carbon monosulphide.
