The catalytic isomerization of substituted vinyl-gem-dichlorocyclopropanes in the presence of a series of zeolite catalysts has been studied. It has been shown that substituted gem-dichlorocyclopentenes are the sole reaction products. The influence of a number of factors (the type of catalyst, temperature, and reaction time) on the yield of isomerization products has been investigated.

取代乙烯基环丙烷的催化异构化

研究了在一系列沸石催化剂存在下取代乙烯基-宝石-二氯环丙烷的催化异构化反应。已经表明取代的偕二氯环戊烯是唯一的反应产物。已经研究了许多因素（催化剂的类型、温度和反应时间）对异构化产物产率的影响。
