SYNTHESIS OF CYCLOPROPANE HYDROCARBONS FROM METHYLCYCLOPROPYL KETONE III - Z-CYCLOPROPYL-1-BUTENE, cis AND trans 2-CYCLOPROPYL-2-BUTENE, AND 2-CYCLOPROPYLBUTANE

摘要

The hydrocarbons - 2-cyclopropyl-l-butene, cis and trans 2-cyclopropyl-2-butene, and 2-cyclopropylbutane - were obtained from methylcyclopropyl ketone by reacting the ketone with ethylmagnesium bromide, dehydrating the resultant methylethylcyclopropylcarbinol to a mixture of olefins from which 2-eyclopropyl-l-butene and cis and trans 2-cyclopropyl-2-butene were isolated, and hydrogenating the olefins to 2-cyclopropylbutane, All four hydrocarbons were obtained in high purity for the first time;their physical constants and infra red spectra are presented.
