γ-Selective Deuteration of Unactivated C(sp3)–H Bonds of Aliphatic Amines via Pd Catalysis in D2O

Abstract Selective γ-deuteration of unactivated C(sp3)–H bonds in aliphatic amines is achieved using D2O as the sole deuterium source via Pd catalysis with 3-formyl-2-pyridone as a transient directing group. The reaction proceeds in aqueous medium without acidic or fluorinated co...
