AbstractQuaternary ammonium salts containing gem-dichlorocyclopropane and 1,3-dioxolane groups were synthesized in high yield. The reactions of dichlorocarbonation of styrene and O-alkylation of 2,2-dimethyl-4-hydroxymethyl-1,3-dioxolane in the presence of quaternary ammonium salts were studied. It was established that in the O-alkylation reaction, compounds containing cycloacetal and allyl moieties
摘要高产率地合成了含有宝石-二氯环丙烷和1,3-二氧戊环基团的季铵盐。研究了季铵盐存在下苯乙烯的二氯碳酸化反应和2,2-二甲基-4-羟甲基-1,3-二氧戊环的O-烷基化反应。已经确定,在O-烷基化反应中,包含环缩醛和烯丙基部分的化合物在所研究的一系列催化剂中具有最大的效率。分离的盐的结构通过1 H和13 C NMR光谱证实。
