A study was conducted to demonstrate the synthesis of a mononuclear biscarbene complex by direct reaction of a Fischer monocarbene complex with a nucleophile addition to a CO ligand. The study proposed mononuclear biscarbene complexes of Group 6, as intermediates in the thermal carbene-carbene coupling reactions of Fischer mononuclear monocarbene complexes. These carbene ligand coupling processes that produced alkenes were reported to occur at room temperature in the presence of palladium(0), or a copper(I) catalyst. It was found that in case of (methyloxy)(aryl)monocarbene complexes, the site of nucleophilic addition is strongly depending on the nature of the organolithium compound. It was found that heteronucleophiles, as lithium amides or potassium alkoxides are also to react with a CO ligand of complexes.
