三苄基氯化锡及其衍生物的合成

摘要/Abstract

摘要： 三苄基氯化锡最初用格氏法制得^[1,2]。Keiti等^[3]曾报道由锡和苄基氯直接制备,这时溶剂对反应的影响很大:用水作溶剂时得到三苄基锡;用甲苯作溶剂时得到二苄基二氯化锡;用正丁醇作溶剂时三苄基氯化锡的产率只有61%^[4]。在反应体系中加入KI、KBr或H₃PO₄等催化剂,三苄基氯化锡的产率也只有60%^[5]。本文用DMF作溶剂,AlCl₃-I₂作催化剂,并首次在反应体系中加入镁、锌、铝和钠等使副产物氯化亚锡还原成活性很高的金属锡^[6],后者再与等基氯反应,可使三苄基氯化锡的产率提高到91.3%。

Abstract: The synthetic method of tribenzyltin chloride has been modified, using DMF as asolvent by reacting tin powder with benzyl chloride and adding magnesium powder to thereactant after disappearing of tin powder. The yield of tirbenzyltin chloride is up to 91%.Compounds of tribenzyltin chloride with isoo tyl thioglycollate, lauric acid and stearicacid have been prepared firstly, they may be used as a PVC stabilizer.

Key words: Tribenzyltin Derivative of tribenzyltin chloride, PVC stabilizer
