摘要：

We report a study on the effect of substituents on the activity of chlorostannoxane catalysts in coupling epoxides and carbon dioxide for cyclic carbonate synthesis. All butyl-substituted (1a) chlorostannoxane was found to yield cyclic carbonates in high turnover number (TON 2340) at 300 psi CO2, 130 degrees C in 2 h. All the reactions were performed under solvent-free conditions in the presence of a Lewis base which acts as a co-catalyst. The activity was found to change with change in the substituents on the catalysts. The effect of change in substituents was studied with respect to variation in essential parameters, such as time, temperature, pressure, and difference in catalyst to co-catalyst ratio.
