The air-stable nickel(II) complex trans-(PCy2Ph)2Ni(o-tolyl)Cl enables an internally selective Mizoroki-Heck-type coupling of substituted benzyl chlorides with terminal alkenes at room temperature. This operationally simple and highly regioselective reaction provides rapid, convergent access to substituted allylbenzene derivatives in high yield and can be carried out on the benchtop with no purification or degassing of solvents or reagents.
