C–H functionalization of benzyl electrophiles with nucleophiles via palladium-catalyzed benzylic C–N cleavage. A range of N-(1-naphthylmethyl)sulfonimides, N-(2-thienylmethyl)sulfonimides, and N-(2-furanylmethyl)sulfonimides smoothly underwent palladium-catalyzed aromatic C–H allylation with allyl Grignard reagents at roomtemperature, delivering structurally diverse substituted 1-allylnaphthalenes and

naphthyl halides is shown to be feasible by employing Grignard reagents. The high reactivity of the nucleophile allows for fast reactions and low catalyst loading, while a plethora of successfully substituted compounds illustrate the broad scope. Five membered heteroaromatic compounds are also demonstrated to be reactive under similar conditions.
