A variety of secondary/primary benzylic, allylic, and aliphatic alcohols are dehydrogenated to the corresponding ketones and aldehydes in high yields of isolated product upon release of H2. This simple catalytic system is involved in the synthesis of imines through the one-pot reaction of alcohols ...
Here we show combining tetra-n-butylammonium decatungstate (TBADT) and cobaloxime pyridine chloride (COPC) can catalytically dehydrogenate unactivated alkanes and alcohols under near-UV irradiation at room temperature with hydrogen as the sole by-product. This noble metal-free process follows a nature...
The highly desirable synthesis of the widely-used primary amides directly from alcohols and ammonia via acceptorless dehydrogenative coupling represents a clean, atom-economical, sustainable process. Nevertheless, such a reaction has not been previously reported, and the existing catalytic systems instead ...
The most active complex bore an electron-rich carbene ligand; this complex was used to catalyse the highly efficient and chemoselective dehydrogenation of a wide range of secondary alcohols to their respective ketones, with turnover numbers up to 1660. Mechanistic studies suggested that the turnover...

The Acceptorless Dehydrogenative Coupling (ADC) of alcohols with amines is reported using a heterogeneous Fe-catalyst. The reaction operates under mild conditions with the liberation of dihydrogen and water as the byproducts. The developed ADC strategy is simple, efficient, exhibits wide functional ...
RHENIUMQUINOLINE derivativesKETONESALDEHYDESA practical and sustainable synthesis of substituted quinolines was achieved through the annulation of 2‐aminobenzyl alcohol with various secondary alcohols, ketones, aldehydes, or nitriles, under hydrogen‐borrowing conditions. Under the catalysis of ...
Herein, we describe the first Co-catalyzed synthesis of 2,3-dihydro-1H-perimidine via acceptorless dehydrogenative annulation (ADA). Apart from featuring benzyl alcohol having different functionalities, heteroaryl and aliphatic alcohols also provide good yields. Our catalytic protocol is also suitable ...
