Abstract

Abstract Alkylidene cyclopropane derivatives are obtained by reaction of biscyclopropyl titanocene with several types of carbonyl compounds, including aldehydes, ketones and esters. In some cases the isomeric vinyl cyclopropane products are also obtained. Biscyclopropyl titanocene also reacts with alkynes forming, after acidification, the corresponding vinyl cyclopropanes.
