The phosphino and (thio)phosphoryl formamides 1a,b, 2a-c, 3a,b, 4a,b which were partially unknown are synthesized by various methods, and their reactions with carbonylmetal halides of manganese and iron are described.The formation of the P,N- and S,N-coordinate chelate complexes, (CO)4MnL (5a, 8a), is limited to the N-phenyl derivatives 1a and 4a.With L = 2a,b, the unidentate P-coordination predominates.Thus, the carbonylmetal halide complexes cis-(CO)4Mn(X)L (6a,b: X = Cl, 7a,b: X = Br) and η5-C5H5(CO)Fe(X)L (9a,b: X = I, 10a,b: X = Br) are obtained.Due to the low stability of the formamide complexes, their formation is always accompanied by isocyanate elimination as a side-reaction. - Key words: Chelate Ligands, Phosphino Formamide, Manganese Complexes, Iron Complexes, Isocyanate Elimination
