Reaction of 1,1-dicyclopropylethylene with pentacarbonyliron: a novel carbon monoxide insertion coupled with a double cyclopropane ring-opening
Abstract
1,1-Dicyclopropylethylene reacts with pentacarbonyliron to give 2-cyclopropylpenta-1,3-dienetricarbonyliron (V) and, after a longer reaction time, a mixture of (V) and 3-(1′-propenyl)-cyclohex-2-enonetricarbonyliron—a carbon monoxide insertion reaction.
