Some dithiocarbamates, thiocarbamates, and thiourea derivatives have been oxidised to the disulphides 1X(R2N=)C>2S2 with iodine.In the presence of trifluoroacetic acid, these lost sulphur giving the thiocarbonyl derivatives R1X(R2N=)C-N(R2)CSR1 (R1, R2, X =3, S; 2, S; Me, Me, S; Et, PhCH2, O; 5α-cholestan-3β-yl, Et, O; and Me, Ph, NMe).These rearrangements were most plausibly intramolecular, but proceeded by varying extents of intermolecular scrambling.
