Chemical and Spectroscopic Studies on Copper Iodide Derived Organocuprates: New Insight into the Composition of Gilman's Reagent

Both 1H and 7Li NMR spectroscopy at high field have served to reveal that the addition of ethereal MeLi to MeCu/THF, in the absence of LiI, leads to unprecedented equilibria (Keq ca. 11) between Me2CuLi and MeLi plus Me3Cu2Li.From a series of spectra at -70 degC, a scheme is proposed to account for the signals observed in solutions of varying MeLi:MeCu ratios.These data lead to the conclusion that not only Gilman's reagent but also "Me3CuLi2" and "Me5Cu3Li2" are not discrete, but rather are composed of differing percentages of the same components.In the presence of LiI, or in Et2O solutions alone, however, this equilibrium does not exi sts for MeLi:MeCu ratios up to 1:1.Chemical tests on both ketones and esters, as well as a series of Gilman tests, fully corroborate the existence of various forms of Gilman's reagent.

Insight into decomposition of formic acid to syngas required for Rh-catalyzed hydroformylation of olefins

Formic acid (FA) is one kind of important bulk chemicals, which is recognized as a sustainable and eco-friendly energy carrier to transport H2 via dehydrogenation or CO via decarbonylation. Expectantly, FA upon decomposition into H2 and CO could be used as the syngas alternative for hydroformylation. In this paper, the behaviors of FA to release H2 as well as CO following the distinct pathways were carefully investigated for the first time, and then established a new hydroformylation protocol free of syngas. It was found that the atmospheric hydroformylation of olefins with formic acid (FA) as syngas alternative was smoothly fulfilled over Xantphos (L1) modified Rh-catalyst under mild conditions (80 °C, Rh concentration 1 mol %, 14 h), resulting in >90% conversion of the olefins along with the high selectivity to the target aldehydes (>93%). By using FA as syngas source, the side-reaction of olefin-hydrogenation was greatly depressed. The in situ FT-IR and the high-pressure 1H NMR spectroscopic analyses were applied to reveal how FA behaves dually as CO surrogate and hydrogen source over L1-Rh(acac)(CO)2 catalytic system, based on which the deeply insight into the catalytic mechanism of hydroformylation of olefins with FA as syngas alternative was offered.

Fischer–Tropsch synthesis with cobalt catalyst and zeolite multibed arrangement

The role of zeolite in transformations of hydrocarbons produced from CO and H2 over a Fischer–Tropsch cobalt catalyst under the conditions of multibed arrangement of the cobalt catalyst and the zeolite has been determined. Hydrocarbon conversion over the HBeta zeolite occurs via the bimolecular mechanism, as evidenced by a low methane yield and a high yield of unsaturated gaseous and liquid hydrocarbons. The conversion over the CaA zeolite obeys the unimolecular mechanism, as evidenced by the formation of increased amounts of methane and saturated gaseous C2–C4 hydrocarbons.
