Abstract

Abstract The diphosphinoamines X 2 PN (R) PX 2 (L)(R= Me or Ph, X= OCH 2 CF 3 or OPh; R= Ph, X= OC 6 H 4 Br-p; R= i Pr, 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) 4 PhN (P (OPh) 2) 2](3d) and cis-[W (CO) 4 i PrN (PPh 2) 2](4f) have been established by single crystal X-ray diffraction studies. Reactions with iron pentacarbonyl yield complexes in ...
