A series of new tetracarbonyl and tricarbonyl complexes of manganese and rhenium with heteroallylic phosphine chelate ligands L = ^- and HXC(Y)PPh2 (X, Y = Nr, O, S) were prepared by reaction of the appropriate metal carbonyl halides with the free ligands or their silyl intermediates.The silyl method yields both cis-(CO)4ML and fac-(CO)3M(X)L (X = Cl, Br) complexes by controlled addition of water.Analytical, spectroscopic and crystallographic data of the ambidentate thioformamide ligands result in a P,S-coordination in all complexes.The 13C NMR spectra ofseveral selected compounds were recorded and reveal some unexpected features.
