A highly chemoselective base-metal catalyzed hydrogenation and acceptorless dehydrogenation of N-heterocycles is presented. well-defined Mn complex operates at low catalyst loading (as as 2 mol %) under mild reaction conditions. The described catalytic system tolerates various functional groups, the corresponding reduced heterocycles can be obtained in high yields. Experimental studies indicate a metal-ligand cooperative catalysis mechanism.

Reductive transformations of easily available oxidized matter are at the heart synthetic manipulation and chemical valorization. The applications catalytic hydrofunctionalization benefit from use liquid reducing agents operationally facile setups. Metal-catalyzed hydroborations provide a highly prolific platform for reductive valorizations stable C=X electrophiles. Here, we report an especially facile, broad-scope reduction various functions including carbonyls, carboxylates, pyridines, carbodiimides, carbonates under very mild conditions with inexpensive pre-catalyst Mn(hmds)2 . reaction could be successfully applied to depolymerizations.
