β，β－（1，5－亚丙二硫基）－α，β－不饱和芳酮的碱分解反应的研究

Studies on The Basic catalysed Decomposition of β,β- (1,5-Dithiopropylene)-α,β-Nnsaturated Arylketones

首次研究了β，β－（１，５－亚丙二硫基）－α，β－不饱合芳酮２的碱分解反应，２类化合物在醇钠的作用下分解生成苯甲酰乙酸乙酯３ａ，２－（１，５－亚丙二硫基）亚甲基苯甲酰丙酮４在醇钠的作用下，加热回流可得到苯甲酰乙酸甲酯３ｂ，如采用边加热回流边蒸溜的方法可得到２－（１，５－亚丙二硫基）－１－苯基－１，３，５－己三酮５。此分解反应为合成苯甲酰乙酸酯类化合物找到一条简便适宜的方法。

The title compunds 2,catalysed by sodium ethylate were decomposed to form 3a in a high yields. At the same condition,4 was decomposed to give 3b,while 4 gived the product 5 with the method of reflux-distillation.
