A photocatalytic hydroaminomethylation of olefins with N‐protected aminomethyltrifluoroborates has been developed. This methodology provides a new strategy for the introduction of a primary aminomethyl group onto electron‐deficient CC bonds. This reaction constitutes a facile entry into synthetically useful γ‐aminobutyric acid (GABA) derivatives such as baclofen.

Although photoredox catalysis is already known for synthesizing amines, the synthesis of linear aliphatic amines is mostly limited to hydroaminomethylation (HAM) reactions and has never been applied to the synthesis of longer-chain linear aliphatic primary amines. Considering this, the synthesis of functionalized linear aliphatic primary amines is demonstrated by using the decarboxylative radical-polar
