The first enantioselective organocatalytic carbo-oxidation of styrenes has been accomplished using singly occupied molecular orbital (SOMO) catalysis. Geometrically constrained radical cations are generated from the one-electron oxidation of enamines formed from the condensation of aldehydes with a secondaryamine catalyst. These SOMO-activated radical cations are susceptible to attack by commercially

A benchmark photoredox alkylation of aldehydes is effectively promoted by using 5 mol‐% of the commercially available [Al(Salen)Cl], in the presence of a MacMillan organocatalyst (14 mol‐%) under irradiation with a CFL light bulb.
