Reactions of some mixed-valence diphosphorus compounds with the platinum(0) complex, (C2H4)Pt(PPh3)2. X-ray crystal structure of the product of the reaction of (C2H4)Pt(PPh3)2 with a λ3Pλ4P+ diphosphorus compound
Abstract The reaction of (C2H4)Pt(PPh3)2(4), with the ionic N,N′-dimethylurea-bridged λ3Pλ4P+ diphosphorus compound, 1b, furnished the mononuclear platinum(II) complex, 6, whose structure was determined by X-ray diffraction. The geometry at platinum shows significant deviation from planarity. The ionic diphosphorus compound, 3a, reacted with 4 to give a PPtPPt four-membered ring system, 7. By contrast
