Alkyl oxalates are new bench-stable alcohol-activating groups for radical generation under visiblelightphotoredox conditions. Using these precursors, the first net redox-neutralcoupling of tertiary and secondary alcohols with electron-deficient alkenes is achieved.

The intermolecular alkylation of pyridine units with simple alkenes has been achieved via a photoredox radical mechanism. This process occurs with complete regiocontrol, where single-electron reduction of halogenated pyridines regiospecifically yields the corresponding radicals in a programmed fashion, and radical addition to alkene substrates occurs with exclusive anti-Markovnikov selectivity. This
