As a carbon-free and sustainable fuel, ammonia serves as high-energy-density hydrogen-storage material. It is important to develop new reactions able to utilize ammonia as a hydrogen source directly. Herein, we report an electrochemical hydrogenation of alkenes, alkynes, and ketones using ammonia as the hydrogen source and carbon electrodes. A variety of heterocycles and functional groups, including for example sulfide, benzyl, benzyl carbamate, and allyl carbamate were well tolerated. Fast stepwise electron transfer and proton transfer processes were proposed to account for the transformation.

The tandem iodoetherification reaction and stereoselective reduction of acyclic redicals has been used in the stereocontrolled synthesis of substituted tetrahydrofurans.Such a tetrahydrofuran intermediate is regioselectively cleaved using Me2BBr to reveal

Radical-based reduction of β-methoxy-or β-fluoro-α-bromo esters could be achieved with good stereoselection at low temperatures.A systematic evaluation of this reaction is presented and possible transition state models are discussed.
