This paper describes the reactions of various thioureas (and several thioamides) with diiron enneacarbonyl. Fully substituted thioureas and thioamides react with Fe2(CO)9 at room temperature to give sulfur-donor ligand iron tetracarbonyl complexes, diiron hexacarbonyl complexes having both nitrogen and sulfur donor ligands, and the known S2Fe3(CO)9. Tetramethylthiourea rather than carbonyl ligand displacement occurred on treatment of tetramethylthioureairon tetracarbonyl with tri-n-butylphosphine. Thioureairon tetracarbonyls and bis(thiourea)iron tricarbonyls, as well as triiron octacarbonyl complexes [and S2Fe3(CO)9], were obtained from reactions of disubstituted and trisubstituted thioureas with Fe2(CO)9. Thiobenzanilide and 5-methyl-3-phenyl-2-thiohydantoin gave similar complexes.
