C−H Activation C−H bond homolysis by hydrogen atom transfer (HAT) usually requires strong oxidants, such as high‐valent metal–oxo compounds. Herein, a nickel(II) complex with an aliphatic PNP pincer ligand that exhibits ligand‐centered protonation and oxidation reactions, which were examined by spectroscopic, electrochemical, crystallographic, and computational analyses is presented. Oxidation enables clean HAT from benzylic hydrocarbons, such as 9,10‐dihydroanthracene, to a ligand backbone vinyl group, which is attributed to the pincer chemical non‐innocence.
