Cobalt carbene ion: Reactions of Co+ with C2H4, cyclo‐C3H6, and cyclo‐C2H4O

Synthesis and Reactions with CO and C2H4 of Cobalt(I) Complexes Containing Trimethylphosphine and Chelating o-Diphenylphosphanyl- phenolate Ligands

In tetracoordinate cobalt(I) halide compounds CoX(Ph2P OH)(PMe3)2 (X = Cl, Br) o-phosphanylphenols Ph2P OH are coordinated as phosphane ligands. In the presence of base chelating anions Ph2P O give rise to pentacoordinate complexes Co(Ph2 P O)(PMe3)3. Molecular structures are presented for both types of compounds. The five-membered chelate ring in Co(Ph2P O)(PMe3)3 is resistant to protonation, ...

Cobalt Loading Effects on the Structure and Activity for Fischer-Tropsch and Water-Gas Shift Reactions of Co/Al2O3 Catalysts

An extensive study of Fischer-Tropsch synthesis (FTS) on alumina-supported cobalt catalysts with different amounts of cobalt is reported. Up to 40 wt % of cobalt, is added to the catalysts by impregnation method. The effect of the cobalt loading on the reducibility of the cobalt oxide species, dispersion of the cobalt, average clusters size, water-gas shift (WGS) activity and activity and s...

Study on Catalytic and Asymmetric Carbene Transfer Reactions Using Chiral (Salen)cobalt(lll) Complexes

Electron Beam Induced Reactions of Adsorbed Cobalt Tricarbonyl Nitrosyl (Co(CO)3NO) Molecules

This study focuses on elucidating the bond breaking steps involved in the electron beam induced deposition (EBID) of nanostructures created from the organometallic precursor cobalt tricarbonyl nitrosyl (Co(CO)3NO) by studying the effect of 500 eV incident electrons on nanometer scale films of Co(CO)3NO. Experiments were performed under ultrahigh vacuum conditions, using a suite of surface analy...

Reactions of Fe+ and FeO+ with C2H2, C2H4, and C2H6: temperature-dependent kinetics.

We present the first temperature-dependent rate constants and branching ratios for the reactions of Fe(+) and FeO(+) with C2H2, C2H4, and C2H6 from 170 to 700 K. Fe(+) is observed to react only by association with the three hydrocarbons, with temperature dependencies of T(-2) to T(-3). FeO(+) reacts with C2H2 and C2H4 at the collision rate over the temperature range, and their respective produc...
