  1. Photochemical synthesis and characterization of mono- and bi-nuclear tungsen tetracarbonyl complexes of 2,2'-biquinoline and 2,3-bis(2- pyridyl) pyrazine

    … synthesized by direct photolysis of the metal hexacarbonyl and indirect route via THF substitution. In the second method, tungsten hexacarbonyl was first irradiated in THF to yield [W(CO)sTHF| and the THF was then replaced by the desired ligand. All complexes were characterised by a combination …

  2. Synthesis and characterization of electrophilic group 4 metal complexes of benzynes

    … synthesis. This benzyne also couples with tungsten hexacarbonyl to afford a Fischer-type metalloxycarbene complex.;Procedures for making the diphenyl precursors [(C5R4 )SiMe2(N-t-Bu)]M(C6H5)2 (R=H, Me; M = Ti, Zr) were developed. Separate coupling reactions involving two of the diphenyl …

  3. METAL NANOMATERIALS: SYNTHESIS, DESIGN, AND APPLICATIONS

    … to different morphologies. Then we proposed a tungsten hexacarbonyl (W(CO)6)-assisted reduction strategy for obtaining uniform metal nanoparticles (e.g., Ir, Ru, Ge, Bi) of different metal salts. This strategy was extended to the synthesis of uniform binary metal (e.g., Sn-Ge) nanoparticles, …

  4. High speed mask-less laser-controlled precision micro-additive manufacture

    … to investigate the ultrafast laser deposition of tungsten from tungsten hexacarbonyl chemical vapour precursors. A 405 nm laser diode was used for continuous wave deposition experiments that were optimized to achieve the lowest track resistivity. These results were used for comparison with the …
