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

Palladium-catalyzed remote sp2–sp3 coupling reaction of chloromethylarenes with allyltrimethoxysilane is described in this work. The allylation reaction regioselectively occurred on the para-positions of 1-(chloromethyl)naphthalenes and benzyl chlorides to form new C(sp2)–C(sp3) bonds. The reaction proceeds smoothly under mild conditions to produce allyl arenes in moderate to excellent yields.

electrophiles with allyl electrophiles has been established. A range of N-benzylsulfonimides smoothly participated in the palladium-catalyzed indium-mediated reductive aromatic C–H allylation with various allyl acetates, delivering structurally diverse allyl(hetero)arenes in moderate to excellent yields with good to excellent site selectivity. The use of inexpensive allylesters for the reductive aromatic
