Reaction of Fe(CO)4CS (1) with PR3 (PR3 = PPh3, PPh2Me) in the presence of ONMe3 gives the substituted derivatives Fe(CO)3(CS)PR3 (2) and Fe(CO)2(CS)(PR3)2 (3) in moderate yields. The compounds have been characterized by inrared, 13C, and 31P NMR spectroscopy. At least two isomers of 2 were identified by IR spectroscopy, the CS ligand is probably in the equatorial position of the trigonal-bipyramidal
