CHEMISTRY OF POLYFUNCTIONAL MOLECULES .117. SYNTHESIS AND MOLECULAR-STRUCTURE OF [CO+1(CO) (2)(PH(2)P-N-P(O)PH(2)(CIRCLE-MINUS)-P)(PH(2)P-NH-PPH(2))]CENTER-DOT-2CH3OH

Reaction of Co-2(Co)(6)(mu-eta(2),eta(2)-HOCH2-C=C-CH2OH-C,C') (5) with Ph(2)P-NH-PPh(2)[bis(diphenylphosphino)amine, dppa, (2), Ph=C6H5] in toluene at 60 degrees C gives [Co+1(CO)(2){Ph(2)P - N - P(O)Ph(2)(c)ircle minus)-P)(Ph(2)P-NH-PPh(2))] (6), in which the ligand dppa was partially oxidized and deprotonated. Recrystallisation of 6 from DMSO/methanol/n-hexane yields 6 . 2 CH3OH. The structure of 6 . 2CH(3)OH was determined by X-ray crystallography. The starting material 5 and 6 . 2CH(3)OH were also characterized by H-1 NMR, C-13{1H} NMR, P-31{H-1} NMR and IR spectroscopy.
