A practical method for the amidation reaction between carboxylic acids and amines was developed, for the first time, through a visible light-mediated photoredox deoxygenation at room temperature.

A general photo-induced regioselective hydroboration of alkenes without photocatalyst or an external initiator has been developed throughin situformed boryl radicals. Thiol plays the dual role as a proton donor and hydrogen atom transfer catalyst.
