Ni-catalyzed reductive allylation of unactivated alkyl halides with allylic carbonates.

Game of two electrophiles: Two partially positively charged sp(3) carbon atoms can be connected by using a catalytic Ni species in the presence of an environmentally benign Zn reductant, delivering allylated alkanes. This unprecedented approach allowed a variety of unactivated alkyl halides and substituted allylic carbonates to regioselectively afford E-alkenes in good to excellent yields.
