Abstract: 1,1,3,3-Tetraorganodistannoxanes are a sort of organotinoxo clusters.They show an excellentcatalytic activity in organic synthesis because they have unique dimeric ladder structures that contain twokinds of five-coordinated tin atoms.Despite of involving a metalloxane core, the distannoxane is quite solu-ble in organic solvents.This is attributable to the double-layered structure of the distannoxanes in whichthe surface alkyl groups prevent the inorganic core from being exposed to the solvent phase.In this articletetraorganodistannoxane-catalyzed esterification of acetic acid and w-butanol was studied.Various cata-lysts,different proportions of acid and alcohol and dosages of catalysts affected this reaction.The mecha-nism of tetraorganodistannoxane-catalyzed esterification is also discussed.

Key words: Tetraorganodistannoxane, Esterification, Catalyst, Mechanism
