Disclosed are highly active cationic cobalt phosphine complexes, both mono- and bimetallic, that can catalyze hydroformylation reactions. The disclosed catalysts can be utilized in methods that provide reaction processes that are hundreds of times faster than high pressure HCo(CO).sub.4 or phosphine-modified HCo(CO).sub.3(PR.sub.3) catalysts and operate at considerably lower pressures and temperatures. Also disclosed are methods of hydroformylation using the described transition metal complexes. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
