Abstract

Scheme I rus compounds has received considerable attention during the past few years.'In these studies it has been shown that phosphorus compounds possessing the common POCCO fragment are subject to a conformational rearrangement around the central CC linkage of this fragment if the coordination state of the phosphorus atom is increased from four (P (1V)) to five (P (V)-TBP). The incorporation of an additional ligand in a P (1V) ...
