The advancement of an effective hydrogen liberation technology from liquid organic hydrogen carriers, particularly cycloalkanes such as cyclohexane and methylcyclohexane, holds significance in realizing a hydrogen-centric society. However, the attainment of homogeneous catalytic acceptorless dehydrogenation characterized by elevated selectivity for thorough aromatization under mild conditions remains unrealized. In this study, a catalyst system, facilitated by a double hydrogen atom transfer processes, has been devised for the catalytic acceptorless dehydrogenation of inert cycloalkanes at ambient temperature under visible light irradiation. Through the synergistic utilization of tetrabutylammonium chloride and thiophosphoric acid hydrogen atom transfer catalysts, successful catalytic acceptorless dehydrogenation with comprehensive aromatization has been accomplished with potential liquid organic hydrogen carrier candidates and showcased high functional group tolerance.

A streamlined strategy for the one-pot synthesis of isoxazolone analogues has been developed through an acceptorless dehydrogenative annulation (ADA) pathway by employing new Ru(II) hydride complexes as effective catalysts. New Ru(II) complexes () tailored with N̂O chelating carbazolone benzhydrazone ligands were synthesized and their formation was confirmed using analytical and spectral techniques including FT-IR and NMR. The structural configuration of the complexes featuring an octahedral geometry around the Ru(II) ion was precisely determined by single-crystal X-ray diffraction analysis.

This study presents a highly efficient and cost-effective Cu/CeO2 catalyst for the acceptorless dehydrogenative coupling (ADC) of o-aminobenzyl alcohols and secondary alcohols to synthesize quinolines. The catalyst demonstrated over 90% yield in quinoline production under mild conditions, exhibiting excellent tolerance to various functional groups. The Cu/CeO2 catalyst, synthesized via a co-precipitation method, was thoroughly characterized through various techniques like PXRD, XPS, and AC-STEM.

Article Synopsis
- First-row transition metals, like Mn(II), play a significant role in acceptorless dehydrogenative coupling reactions, making it important to study their catalytic mechanisms for better catalyst design.
- This research utilized density functional theory (DFT) to analyze a novel dehydrogenation pathway involving a high-spin Mn(II) complex, where an external base (KOH) interacts with the metal center for the reaction.
- The study identified the hydride transfer as the rate-determining step with an energy barrier of 26.3 kcal/mol, while also highlighting how factors like small steric hindrance and strong orbital interactions of KOH influence the reaction's selectivity.
