The Extremely Rapid Acid-catalysed Isomerizations of Carbonyl-Mo or -W Tertiary Phosphine Complexes: Convenient Syntheses of fac- or mer-Isomers

Acid, at a concentration frequently present in solvents such as dichloromethane, causes rapid interconversion of fac- and mer- (dppm=Ph2PCH2PPh2, L=PEt3 or PEt2Ph) via a 7-co-ordinate hydride intermediate, +: convenient syntheses are developed, based on these protonation reactions, including the conversion of fac- into the more useful mer-isomer.

The new complexes fac- and mer- (dppm = Ph2PCH2PPh2) are described.Treatment of fac- or mer- (M = Cr, Mo, or W) with trans- gave the heterobimetallic complexes in good yields.Similarly fac- or mer- reacted with trans-CPh)(PPh3)2> to give CPh)>, but the corresponding chromium- or tungsten-platinum complexes could not be prepared.Phosphorus-31 and 1H n.m.r., and i.r. spectroscopic data are given and discussed. 1H- N.m.r. studies at different temperatures showed the complexes of type (M = Cr, Mo, or W, Y = Cl; M = Mo, Y = CCPh) to be fluxional, corresponding to inversion of the M(μ-dppm)2Pt ring and exchange of positions of the H and Y ligands: a mechanism for this inversion is suggested.The chloride ligand of was found to be readily substituted by nucleophiles Y (Y = Br, CN, N3, H, or CO) to give new heterobimetallic species.Treatment of with NaBH4 gave a heterobimetallic dihydride with a bridging and a terminal hydride. 1H- N.m.r. studies showed this dihydride to undergo bridging-to-terminal hydride exchange at +21 deg C in solution.
