We report a redox‐neutral method for the generation of carbanions from benzylic C–H bonds in a photocatalytic Grignardtype reaction. The combination of photo‐ and hydrogen atom transfer (HAT) catalysis enables the abstraction of a benzylic hydrogen atom, generating a radical intermediate. This radical is reduced in situ by the organic photocatalyst to a carbanion, which is able to react with electrophiles such as aldehydes or ketones, yielding homobenzylic secondary and tertiary alcohols.
