A series of carbonyl-based homogeneous catalyst precursors has been prepared. These species include: Fe(CO){sub 4}PPh{sub 3}, Fe(CO){sub 3}(PPh{sub 3}){sub 2}, Fe(CO){sub 2}(PPh{sub 3}){sub 2}CS{sub 2}, S{sub 2}Fe{sub 2}(CO){sub 6}, S{sub 2}Fe{sub 3}(CO){sub 9}. Fe(CO){sub 4}PPh{sub 3} was prepared by a combined photochemical and thermal route from triphenylphosphine (PPh{sub 3}) in iron pentacarbonyl (Fe(CO){sub 5}). This preparation procedure, which is selective to the monosubstituted product, is outlined herein. Currently these compounds are being tested as catalysts/catalyst precursors with coal or model compounds in the tubing bomb reactors to provide information relating catalytic activity to catalyst structure and properties.
