Partial and complete dichlorocarbenation of conjugated diene hydrocarbons in the presence of the phase-transfer catalyst catamine AB has been studied. It has been shown that at the initial stages of the process (conversion of the reactant olefins below 30%), alkenyl-gem-dichlorocyclopropanes are the main products. In the case of complete carbenation, corresponding bicyclic structures are formed. The
已经研究了在相转移催化剂猫胺AB存在下共轭二烯烃的部分和完全二氯碳化。已经表明,在该方法的初始阶段(反应物烯烃的转化率低于30%),烯基-宝石-二氯环丙烷是主要产物。在完全碳酸氢盐的情况下,形成了相应的双环结构。所得立体异构体的结构已在使用详细地描述了1 H和13种СNMR方法。初始二烯的相对反应性已使用竞争动力学方法确定。
