Conclusions 1. We have shown the feasibility of catalytic activation of CS2 in the reaction with butadiene in the presence of the Pd(acac)2-PPh3-AlEt3 system, 1,2-bis(diphenylphosphino)ethane, and promoters (a mixture of CO2 and NH3), to obtain in single stage substituted 1,4-dithio- and 1,4-di(thioxo)cyclohexanes with high yields. 2. We discovered that the heterocyclization of CS2 with butadiene is accompanied by a selective oxidation of the produced tetramethyl-1,4-dithiqcyclohexanes to the corresponding 1,4-bis-sulfoxides with the aid of CO2, under the action of palladium complexes.
