Abstract A series of tetraorganodistannoxane have been synthesized from the reaction of R2SnO and R'2SnX2 by microwave. Results of conventional heating and microwave activation have been presented. Microwave irradiation reaction in the presence of solvent and in the absence of solvent has been compared, influence of microwave power and solvent has been studied. Microwave irradiation has significant rate enhancements to the synthesis of distannoxane.

摘要 利用R2SnO与R'2SnCl2的反应合成了系列不同烃基的四烃基二锡氧烷，对比了常规加热回流与微波辐射条件下的反应时间与产物得率，比较了固相反应与液相反应，微波功率与使用溶剂间的关系。结果表明微波对这类化合物的合成有较好的促进作用。
