Trimethylphosphine-Tungsten Chemistry: Hydrido, Silyl, Fluoro, Hydroxy, and Aquo Derivatives: Crystal Structure of F

The compounds W(PMe3)4H2X2 (X = H, F, SiH3), 2+->2, and F, whose crystal structure has been determined, are described; W(PMe3)4(η2-CH2PMe2)H reacts with ethylene giving inter alia W(η

Hexakis(trimethylphosphine)molybdenum Chemistry: Dinitrogen, Ethylene, Butadiene, η-Cyclopentadienyl, and Related Derivatives

Co-condensation of molybdenum atoms with trimethylphosphine gives octahedral (1) whose crystal structure has been determined.Treatment of (1) with dinitrogen, ethylene, carbon monoxide, iodine, or butadiene gives , trans-, fac-, trans-, and cis- respectively.Protonation of cis- with tetrafluoroboric acid forms the compound .The presence of the Mo-H-C bond is shown by low-temperature n.m.r. spectra, and variable-temperature n.m.r. shows that the agostic hydrogen can scramble between the four terminal carbons of the two C4 ligands.The rate constants and activation parameters for the hydrogen-scrambling process have been determined and a mechanism is proposed.Reaction of cis- with trifluoroacetic acid gives .Treatment of with cyclopentadiene forms which reacts with aqueous tetrafluoroboric acid giving BF4 and BF4.Reaction of with methyl iodide gives .

Synthesis of Hexakis(trimethylphosphine)molybdenum using Molybdenum Atoms and its X-Ray Crystal Structure

Co-condensation of molybdenum atoms with an excess of trimethylphosphine gives hexakis(trimethylphosphine)molybdenum which crystal structure studies show to have an octahedral MoP6 unit; it is highly reactive to substitution by dinitrogen, olefins, and dihydrogen, forming a variety of derivatives.
