In this paper we report the outcome of the reduction of NHC stabilized acetylenic dications, [NHC-C -NHC] for n=2 and 4. The target compounds were NHC stabilized di- A nd tetracarbon in the form of NHC-C -NHC. However, upon chemical reduction, decomposition ensues with release of the free NHC. This effect is also observed in electrochemical studies. This lends credence to Bestman's hypothesis that two donor ligands cannot stabilize C for n=even numbers.
