✦ Synopsis
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.

## Abstract The reaction is applied to a variety of primary and secondary halides with both coupling partners being bromides or a bromide and an iodide.
Nickel-and palladium-catalyzed cross-coupling reactions of organic halides with organometallic reagents is one of the most versatile carbon±carbon bond-forming reactions in organic synthesis. [1] In most cases, aryl and vinyl halides are employed as organic halides, yielding sp 2 ±sp, sp 2 ±sp 2 , a
