  A new type of chemical cascade reaction was found: the direct formation of cyclopropanes from carbonyl compounds and C–H acid. The action of free halogen or active halogen containing compounds on a mixture of 1 equiv of carbonyl compound and 2 equiv of malononitrile in a basic alcohol solution results in the formation of substituted 1,1,2,2-tetracyanocyclopropanes in 15–80% yield. The latter are well-known

  发现了一种新型的化学级联反应：由羰基化合物和CHH酸直接形成环丙烷。游离卤素或含活性卤素的化合物在碱性醇溶液中对1当量羰基化合物和2当量丙二腈的混合物的作用导致形成取代的1,1,2,2-四氰基环丙烷，产率为15-80％ 。后者是用于不同双环杂系统的众所周知的前体，其中包括含有环丙烷环并具有不同类型药理活性的化合物。因此，直接从诸如醛，某些环酮或取代的环己酮和丙二腈之类的简单而合理的起始化合物中直接发现了一种新的，简单而有效的“一锅法”，以50-80％的产率取代四氰基环丙烷。
