The cycloaddition of epoxides with carbon disulfide proceeds effectively by using a binary catalyst system of tetradentate Schiff-base aluminum complexes (designated as SalenAlX) as electrophile in connection with quaternary ammonium salt as nucleophile. The steric factor of the substituent goups on the aromatic rings of SalenAlX and the anion of quaternary ammonium salt all have significant effects on the activity of the binary catalyst system, as well as the selectivities of the resulting cyclic products. The effects of temperature, time and the molar ratio of reactants were also investigated in detail with regard to propylene oxide with carbon disulfide, and a plausible mechanism was proposed.
Keywords:Thiocarbonates；Carbon disulfide；Tetradentate Schiff-base aluminum complexes；Quaternary ammonium salt; cooperative catalysis
