N-heterocyclic carbenes (NHC's) are commonly used as s-donating ligands in catalytic transition metal complexes.  Similar to rhodium phosphines, rhodium NHC complexes are of interest for their capability of performing a wide variety of catalytic transformations.  In this work, the complex [(cod)Rh(NHC)H2O]BF4 (cod = cyclooctadiene, NHC = 1,3-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene) was synthesized and characterized by X-ray crystallography and NMR studies.  Herein, the unique solid-state structure of the aqua adduct will be detailed along with the initial results of the complex's use in catalytic amination reactions.
