A simple, efficient, facile and eco-friendly process for the synthesis of thioamides from nitriles using 1,6-bis(3methylimidazolium-1-yl)hexane chloride [C6(mim)2Cl2] as a dicationic ionic liquid (DIL) was developed. The ionic liquid was easily separated from the reaction mixture and was recycled at least four times without any loss of its activity.

The thermal rearrangement of 1,2-dimethyl-1,2-di(thioaroyl)hydrazines to bis(N-methylarylimidoyl) disulfides was realized.It is suggested that the transformation takes place by a concerted -sigmatropic shift mechanism.

Reactions of α-aryl-N-methylnitrones with phenylphosphonothioic dichloride (1), diphenylphosphinothioic chloride (6), or thiophosphoryl trichloride (7) gave N-methylbenzamide and N-methylthiobenzamide derivatives, and the latter became major in the presence of tertiary amine. α,N-Diarylnitrones (4) reacted with 1 to give 2-arylbenzothiazoles (5) at room temperature in moderate yields.Reaction of 4 with 6 (at room temperature) or 7 (in refluxing THF) gave 5 in a low yield, whereas a similar reaction of 4 with 7 at 0 deg C afforded N-benzylidene-2-chloroaniline in a high yield.A mechanism for the formation of 5 has been discussed briefly.
