Significance

A photoredox cobalt-catalyzed ­enantioselective approach to a Grignard-type addition of aryl iodides to aldehydes is reported. Notably, the mild reaction conditions enable a wide range of functional groups and heterocycles to be tolerated.

Comment

4CzIPN is used as the photocatalyst, which can be excited under visible-light irradiation. The use of Hantzsch ester as the reductant is notable because it avoids the generation of stoichiometric metal waste.
