The cyclic vinylcyclopropane 6a reacts at elevated temperatures with iron pentacarbonyl to selectively give the enone 7a in 52% yield. Reducing the reaction time provided the isomeric ketones 7a – b . Partial chromatographic separation of this mixture allowed the complete spectroscopic identification of 7b by 1 H NMR. The structure of 7c was determined from selected spectral data of the mixture of 7a and 7c . For comparison, the methyl substituted derivate 6b was subjected to a carbonylation under the above conditions exclusively providing 8 ini 42% yield. A mechanistic rationale for the two different modes of ring opening is presented. |
