摘要

The decarboxylation of several half-esters of a, &unsaturated malonic acids in pyridine has been investigated for the purpose of determining the influence of the a, p-ethylenic linkage on such systems. The decarboxylation of ethyl hydrogen isopropylidenemalonate (11) proceeds rapidly in pyridine (111") and affords a mixture of ethyl 8-methyl-8-butenoate (IV) and ethyl@,@-dimethylacrylate (111)(ratio, 3: 1). The reaction has been studied kinetically ...
