    • A novel process is disclosed for the preparation of cyano-substituted cyclopropane derivatives of the following general formula: ##STR1## wherein R.sub.1, R.sub.2 and Hal have the meanings given in the description. The process comprises the steps of cyclizing and dehydrohalogenating, in the presence of a base, a 4,6,6,6-tetrahalo-2-cyano-3,3-dialkylhexanoic acid or an alkyl ester thereof, followed by thermal decarboxylation of the resulting cyclized and dehydrohalogenated product. Under selected conditions cyclization, dehydrohalogenation and decarboxylation occur simultaneously in one reaction zone. The resulting cyano-substituted cyclopropane derivatives are useful as intermediates in the production of insecticidally active compounds.
    • 公开了用于制备以下通式的氰基取代的环丙烷衍生物的新方法:其中R1,R2和Hal具有说明书中给出的含义。 该方法包括在碱存在下将4,6,6,6-四卤代-2-氰基-3,3-二烷基己酸或其烷基酯环化和脱卤化氢的步骤,接着热脱羧 得到环化和脱卤化氢产物。 在选择的条件下环化,脱卤化氢和脱羧反应同时发生在一个反应​​区。 得到的氰基取代的环丙烷衍生物可用作杀虫活性化合物生产中的中间体。
