The compound Ph2PN(H)PPh2 (I) reacts under special conditions with M(CO)6 (M=Cr, Mo), Fe(NO)2(CO)2 and Co(NO)(CO)3 to give the new complexes cis-M(CO)22 (III, IV), 2NH (V), 2 (VI) and Co(NO)(CO)2Ph2PN(H)PPh2 (VII).Compound VI can also be prepared by reacting V with I.For III and IV proton NMR spectra indicate some interaction between o-protons of the phenyl rings and the cis-M(CO)2 groups.VI exists as an eight-membered ring complex without a metal-metal bond.On the basis of spectroscopic data VII seems to exist in two conformers.

Several unexpected reactions have led to syntheses of cis- in which E = O, S, NH.The E = O complex was obtained from the reactions of several acid chlorides (CH3C(O)Cl, PCl3, (MeO)P(O)Cl2 and ) with + cis--.The E = NH analog aeose from the reaction of BF3*O(C2H5)2 with cis- and the E = S complex resulted from the reaction of H2S with cis-.The unsymmetrically subsituted complex cis- was obtained from the reaction of cis- with excess sodium ethoxide in ethanol.Cleavage of a P-S bond in cis- with NaOH in the presence of Et4N+Cl- yielded the unsymmetrical complex + cis--.Synthesis of cis- was accomplished by reacting (ClCH2)P(O)(OH)2 with cis-.Multinuclear NMR (1H, 13C, 17O, 31P) and IR spectroscopy assisted in complex characterization.Conductance measurements on acetone solutions proved the complexes + cis--, where E = H+, BF2+, and + cis--, where Y = O, S, to be 1/1 electrolytes.
