چکیده
Catalytic dehydrogenation of alcohols represents an attractive approach for future applications as hydrogen storage systems and clean synthesis fine chemicals. Herein, overview recent progress in homogeneously catalyzed acceptorless alcohol is presented. In Nature, efficiently by multiple metalloenzymes where a non-noble metal–ligand interplay key to activate transform substrate. We highlight the introduction multifunctional cooperative ligands coordination sphere metal center order improve catalytic activity under photochemical, electrochemical or thermal conditions. Moreover, cooperativity crucial easy transition first row based catalysis, we have seen years.

A reusable unsupported rhenium nanocrystalline catalyst for acceptorless dehydrogenation of alcohols through γ-C-H activation.
Rhenium nanocrystalline particles (Re NPs), of 2 nm size, were prepared from NH4ReO4 under mild conditions in neat alcohol. The unsupported Re NPs convert secondary and benzylic alcohols to ketones and aldehydes, respectively, through catalytic acceptorless dehydrogenation (AD). The oxidant- and acceptor-free neat dehydrogenation of alcohols to obtain dihydrogen gas is a green and atom-economic...
متن کاملWell-Defined Iron Catalysts for the Acceptorless Reversible Dehydrogenation-Hydrogenation of Alcohols and Ketones
Acceptorless dehydrogenation of alcohols, an important organic transformation, was accomplished with welldefined and inexpensive iron-based catalysts supported by a cooperating PNP pincer ligand. Benzylic and aliphatic secondary alcohols were dehydrogenated to the corresponding ketones in good isolated yields upon release of dihydrogen. Primary alcohols were dehydrogenated to esters and lactone...
متن کاملAcceptorless dehydrogenation of small molecules through cooperative base metal catalysis.
The dehydrogenation of unactivated alkanes is an important transformation both in industrial and biological systems. Recent efforts towards this reaction have revolved around high temperature, organometallic C-H activation by noble metal catalysts that produce alkenes and hydrogen gas as the sole products. Conversely, natural desaturase systems proceed through stepwise hydrogen atom transfer at...
متن کاملSubstitution of alcohols by N-nucleophiles via transition metal-catalyzed dehydrogenation.
Transition metal-catalyzed substitution of alcohols by N-nucleophiles (or N-alkylation of amines and related compounds with alcohols) avoids the use of alkylating agents by means of borrowing hydrogen (BH) activation of the alcohol substrates. Water is produced as the only by-product, which makes the "BH" processes atom-economic and environmentally benign. Diverse types of homogeneous organomet...
متن کاملPalladium Catalyzed Aerobic Dehydrogenation: From Alcohols to Indoles and Asymmetric Catalysis
Catalytic aerobic dehydrogenation of organic substrates is going through a Renaissance. Recent advances in this area have led to the discovery of palladium-catalyzed alcohol dehydrogenations and oxidative heteroand carbocyclizations. The development of asymmetric catalytic dehydrogenations is the latest advance in a long line of catalytic asymmetric oxidation reactions. Introduction Asymmetric ...
