Abstract: A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H2. The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.

Abstract: Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the catalytic dehydrocoupling of ethanol to produce ethyl acetate and hydrogen. As both ethanol and ethyl acetate are volatile materials, they can be readily separated from the catalyst by applying vacuum at room temperature. The hydrogen by-product of the reaction may be isolated and utilized as a feedstock in other chemical transformations.

Abstract: Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the transfer hydrogenation of esters using C2-C12 alcohols as sacrificial hydrogen donors to produce corresponding alcohols from the esters. No external H2 pressure is required. The reaction can be carried out under ambient pressure.
