Abstract

New cationic P-coordinated (diphenylphosphino)alkyne complexes with molybdenum [(Mp)Ph2PC≡CR][BF4] {R = H, Me, tBu, Ph, Tol; Mp = (C5H5)Mo(CO)3} have been prepared from reaction between a (diphenylphosphino)alkyne Ph2PC≡CR and the dinuclear complex [(C5H5)Mo(CO)3]2, with Ag(I) as oxidant. The bis(diphenyphosphosphino)acetylene Ph2PC≡CPPh2 led to the following homo- and heteronuclear metal complexes by the same method: [(Mp)Ph2PC≡CPPh2][BF4], [(Mp)Ph2PC≡ CPPh2(Mp)][BF4]2 and [(Mp)Ph2PC≡CPPh2(Fp)][BF4]2 (Fp = (C5H5)Fe(CO)2}. The reaction of the P-coordinated molybdenum complexes [(Mp)Ph2PC≡CR][BF4] with dicobalt octacarbonyl at room temperature afforded the cationic heterometallic complexes [(Mp)Ph2PC2R{Co2(CO)6}][BF 4]. All complexes were characterised by microanalysis and IR, 1H-, 13C- and 31P-NMR spectroscopy. © 2000 Published by Elsevier Science S.A. All rights reserved.
