A new compound of the formula: (Bu4N)2[Zn(4-CH3C6H4SO2NCS2)2] (Bu4N = tetrabutylammonium cation) was obtained by the reaction of CH3C6H4SO2NCS2K2 · 2H2O with zinc(II) acetate dihydrate and tetrabutylammonium bromide in dimethylformamide. The elemental analyses of C, H, N and Zn are consistent with the proposed formula. The IR data point to the formation of a zinc(II)–bis(dithiocarbimato) complex. The 1H NMR and 13C NMR spectra showed the expected signals for the tetrabutylammonium cation and the dithiocarbimato moiety. This compound was evaluated as for the vulcanization activity and compared to the commercial accelerators CBS, MBTS and TMTD. These studies showed that the zinc(II)–ditiocarbimates are a new class of rubber vulcanization accelerators, worth of further investigation.
