| Abstract: | Three tetraorganodistannoxanes containing silicon were synthesized and their catalytic properties in esterification and acetalization
were observed via the reactions of acetic acid with isoamyl alcohol and butyraldehyde with glycol. The factors affecting the reaction, such
as the catalyst dosage, reaction time and solvent, etc. were discussed. The results show that the three tetraorganodistannoxanes
displayed similar good catalytic activities compared to dichlorotetrabutyldistannoxane in esterification and acetalization.
When the dosage of ClBu2SnOSn-(CH2SiMe3)2Cl]2 was 1.5% based on the mass of reactant, the yield of isoamyl acetate was 91.8% and the yield of butyraldehyde glycol acetal
94.2%. The different alkyl and bridging groups on Sn sites in the structure of tetraorganodistannoxanes showed some influence
on the catalytic activities of these compounds.
