Popis: Sn(IV) complexes (dimethyltin dineodecanoate (1), dibutyltin dineodecanoate (2), dioctyltin dineodecanoate (3), dimethyltin diundec-10-enoate (4), dibutyltin diundec-10-enoate (5), tributyltin undec-10-enoate (6) and tributyltin undecanoate (7)) were tested as catalysts for transesterification or esterification in the presence of methanol, in order to investigate the effect of the substituents coordinated to the metal center. All complexes were active at relative high reaction temperatures, and their reactivity can be associated with the steric effects induced by the substituents (alkyls and carboxylates) at the metal center.
