Dehydrogenative Coupling

The nickel-catalysed dehydrogenative coupling of 1,2-di-amino-benzene with primary alcohols and diols for the synthesis of N-heterocycles is reported. The catalytic protocol enables the transformation in up to 91% yield and generates water and hydrogen gas as byproducts.

Dehydrogenative Coupling

Herein, we developed a simple iron-catalyzed system for the α-alkenylation of ketones using primary alcohols. Such acceptor-less dehydrogenative coupling (ADC) of alcohols resulted in the synthesis of a series of important α,β-unsaturated functionalized ketones, having aryl, heteroaryl, alkyl, nitro, nitrile and trifluoro-methyl, as well as halogen moieties, with excellent yields and selectivity. Initial mechanistic studies, including deuterium labeling experiments, determination of rate and order of the reaction, and quantitative determination of H2 gas, were performed. The overall transformations produce water and dihydrogen as byproducts.

Valorization of biomass has become an area of intense focus because of the diminishing reserves of crude oil and the ongoing problem of climate change. The principal strategies for the utilization of biomass as a feedstock are (i) to produce biofuels for the transportation sector and (ii) to produce organic commodity chemicals. In this respect, we have developed a serious of manganese-catalyzed dehydrogenative/deoxygenative coupling reactions of lower alcohols, obtainable from oxygen-rich lignocellulosic biomass, to deliver advanced liquid fuels and valuable chemicals.1 Introduction2 Manganese-Catalyzed Upgrading of Ethanol to Butan-1-ol3 Manganese-Catalyzed Selective Upgrading of Ethanol with Methanol to Isobutanol4 Manganese-Catalyzed Acceptorless Dehydrogenative Coupling of Alcohols with Hydroxides to Give Carboxylates5 Manganese-Catalyzed Dual-Deoxygenative Coupling of Primary Alcohols with 2-Arylethanols6 Conclusion
