Novel three-coordinate Fe complexes featuring 1,2-diphenyl-3,5-bis(2,6-dimethylphenoxy)pyrazolin-4-ylidine or “cyclic bent allene” (CBA) have been synthesized. Reaction with FeCl2(PPh3)2 results in the loss of both phosphines to yield monomeric Fe(CBA)Cl2. Treatment with 2 equiv of benzyl Grignard affords the three-coordinate alkylated product Fe(CBA)(Bn)2. Exposure of the alkylated species to an atmosphere

Uranyl–carbon bonds are rare due to the limited numbers of synthetic routes. The synthesis of carbodicarbene uranylcomplexes is reported, along with complete spectroscopic and structural characterization. These data along with a computational analysis confirm strong electron donation by the carbodicarbene ligand, as well as a single-bond order between the uranium(VI) ion and the carbon.
