Abstract: Triorganotin compounds are a kind of organotin complexes with high biological activities. Some of triphenyltin derivatives such as triphenyltin acetate and triphenyltin hydroxide have been used as agricultural chemicals^[1]. α-Oxo ketene dithioacetals is a kind of important polyfunctionai intermediates in organic synthesis and is widely studied in recent years^[2]. Some of α-oxo ketene dithioacetal derivatives, such as 1,3-dithio-2-cyclopentylene-dithiopropylacrylate has also been used as agricultural chemicals. But it is no reports about the work combined both trialkyltin derivatives and α-oxo ketene dithioacetals together.
