摘要

The condensation of aliphatic diazo compounds with olefins containing an activated double bond is known to result in the formation of pyrazolines.'This reaction has been studied in considerable detail, for pyrazolines are easily converted to pyrazoles by oxidation'or to substituted cyclopropanes by heat. 2'We were interested in determining the course of reaction between nitroolefins and diazo compounds for the possibility existed that such a ...
