Abstract

The diphosphinoamines $X_2PN(R)PX_2 (L) (R = Me or Ph, X = OCH_2CF_3 $or OPh; $R = Ph, X = OC_6H_4Br-p; R = ^iPr, X = Ph)$ react with group 6 metal carbonyl derivatives to yield the cis-chelate complexes [M(CO)4(L-PP′)]. The structures of cis-$[Mo(CO)_4PhN(P(OPh)_2)_2]$(3d) and cis$-[W(CO)_4\hspace{1mm}^iPrN(PPh_2)_2]$ (4f) have been established by single crystal X-ray diffraction studies. Reactions with iron pentacarbonyl yield complexes in which a chelating or a bridged-bidentate mode of coordination of the ligands is observed.
