Synthesis of Acetophenone Cylic Ethylic Ketal Catalyzed by Organotin Compounds Containing Silicon

The catalytic properties of organotin compounds containing silicon,bis((trimethylsilyl) methyl) tin dichloride and tri((trimethylsilyl)methyl) tin chloride,were observed in the synthesis of acetophenone cylic ethylic ketal.The factors which affected the reactions,such as catalyst dosage,reaction time,and solvent kind etc.,were discussed.The results showed that organotin compounds containing silicon exhibited good catalytic activities for synthesis of acetophenone cylic ethylic ketal.The yield reached 85.1 %...
