eng C,N-chelated organotin(IV) species with weakly coordinating carborane moieties: Potential catalysts of the direct synthesis of dimethyl carbonate?! Organotin(IV) species bearing the 2-(N,N-dimethylaminomethyl)phenyl- moiety as a C,N-chelating ligand (LCN) are studied since seventieth of the last century.1 Significant intramolecular contact between tin and nitrogen atoms is the typical phenomenon for this class of compounds. We reported previously on the structure and reactivity of some novel C,N-chelated organotin(IV) trifluoroacetates and triflates that were tested as potential catalysts for the direct synthesis of dimethyl carbonate (DMC) from CO2 and methanol (Scheme 1). Recent results concerning the preparation, characterization and catalytic activity studies of the two novel C,N-chelated organotin(IV) species bearing carborane (e.g. CB11H12) moieties will be discussed in detail.
