Construction of stereogenic carbon centers of propargylic alcohols with free radicals could mark a simple route to molecular complexity from easily obtained starting materials. Here the authors present a strategy to control enantioselective propargyl

Abstract The Diels‐Alder reaction of cyclopentadiene with methyl acrylate catalyzed by AlCl3 has been theoretically investigated. M06‐2X level DFT calculations have shown that the formation of two C−C bonds is asynchronous in the cycloaddition

Conical intersections (CIs), which indicate the crossing of two or more adiabatic electronic states, are crucial in the mechanisms of photophysical, photochemical, and photobiological processes. Although various geometries and energy levels have been

Earth-abundant metal-catalyzed oxidative conversion of ammonia into dinitrogen is a promising process to utilize ammonia as a transportation fuel. Herein, we report the manganese-catalyzed ammonia oxidation under chemical or electrochemical condition

We recently proposed a transition-state model for asymmetric propargylic substitution reactions of propargylic alcohols catalyzed by optically active thiolate-bridged diruthenium complexes [Chem. - Asian J.2021, 16, 3760-3766]. In the present study,

The development of transition metal-catalyzed enantioselective propargylic substitution reactions has gained much progress in recent years, however, no successful example with phosphorus-centered nucleophiles has yet been reported until now. Herein,
