The reaction of gem-dihalogenocyclopropanes derivatives with (tetracarbonyl)(methoxycarbonylato)ferrate(I−) has been investigated; gem-dibromocyclopropanes and gem-chlorobromocyclopropane derivatives are reduced and carbonylated. It could be shown that a bromo ester such as methyl 1-bromo-2-phenylcyclopropanecarboxylate is an intermediate in the transformation of 1,1-dibromo-2-phenylcyclopropane into methyl cis- and trans-2-phenylcyclopropanecarboxylates and dimethyl 2-phenyl-1,1-cyclopropanedicarboxylate.
研究了偕二卤代环丙烷衍生物与(四羰基)(甲氧基羰基)铁酸盐(I−)的反应;偕二溴环丙烷和偕氯溴环丙烷衍生物被还原和羰基化。可以证明,溴代酯如1-溴-2-苯基环丙烷甲酸甲酯是1,1-二溴-2-苯基环丙烷转化为顺式和反式-2-苯基环丙烷甲酸甲酯和2-苯基环丙烷二甲酯的中间体。 1,1-环丙烷二甲酸酯。
