We report here that a cobalt catalyst generated from a cobalt(II) salt and a ligand using magnesium metal is capable of promoting hydroarylation reactions through chelation‐assisted C−H activation. With the appropriate choice of the ligand and other reaction conditions, ketimine‐ or aldimine‐directed branched selective hydroarylations of styrenes and ketimine‐directed hydroarylations of vinylsilane
