N2 - A series of neutral hexacoordinate X6 phosphorus i I compounds of the general formula (CF3)nPN(R)C(Cl)N(R) (n = 0, 1, 2, 3; R = cyclohexyl, isopropyl) has been prepared. The parent compounds are obtained by “insertion” of carbodiimide into the P-Cl bond of a X5-chlorophosphorane. Substituted pyridines also react readily with X5 chloro and fluor° phosphoranes to form 2-methylamino, thio and oxopyridine chelates of the form X4P(Epy) (E = O, NMe and S; X - F, Cl) in which the phosphorus achieves six coordination through acceptance of the pyridine nitrogen. Selected reactions and the fluxional behavior of the X6 systems are discussed.
