Novel mono- and dinuclear dimethyltin(IV) complexes were synthesized using tridentate Schiff base ligands, derived from 2-amino-2-hydroxymethyl-propane-1,3-diol and various aldehydes. These diorganotin(IV) compounds displayed good catalytic activity for solvent-free cycloaddition of CO2 to epoxides at ambient pressure. These catalysts efficiently completed the insertion of CO2 to various epoxides at low catalyst loadings (0.1-1.0 mol%) in 1-6 hours giving high values of TONs around 1000. The catalyst further usability for three continuous reaction runs in the reaction mixture gives the same ac...
