This protocol employing a chiral Ni/PHOX catalytic system allows terminal and internal alkenes to successfully engage the arylalkylation with exquisite control of regio-, chemo-, and stereoselectivity. More importantly, this reductive arylalkylation undergoes regio- and enantioselective arylnickelation followed by radical cross-coupling via Csp3–Csp3 reductive elimination, thus exhibiting reverse regioselectivity
