Abstract:
Cross-electrophile coupling reactions of different electrophiles have been extensively studied but mainly limited to bromides and iodides. Here, we report an electrochemically induced nickel-catalyzed cross-electrophile coupling strategy between alkenyl triflates and α-chloroamides in an undivided cell under mild reaction conditions, affording the α-functionalized amide derivatives in good to excellent yields with broad substrate scopes and good functional group tolerance. The control experiments were conducted, and a plausible mechanism was proposed.

Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...

Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
