Description

This project aims to photochemically generate cyclopropylidene, the smallest cyclic carbene. This highly unstable species, which contains a carbon with two unpaired valence electrons, has been of great interest for several decades to experimentalists and theoreticians. Yet, the trapping of cyclopropylidene has not been previously reported. In this work, we have generated a novel phenanthrene-based precursor to this carbene via a four-step synthesis using solution based methods. Preliminary results indicate that cycloproylidene can be photochemically trapped by alkenes and further work will seek to trap this carbene with other reagents.
