A new and facile protocol for the synthesis of dithiocarabamate in EtOH/H2O is described. Reaction of aromatic and aliphatic amines with CS2 and 3,4-dihydro-2H-pyran in the presence of N,N,N',N'-tetrabromobenzene- 1,3-disulfonamide [TBBDA] and poly(N-bromo-N-ethylbenzene-1,3-disulfonamide) [PBBS] gives the corresponding dithiocarbamates in good to high yields.
