WebDec 3, 2024 · In summary, we report a Ni-catalyzed regioselective alkene dialkylation reaction with benzyl bromides and alkylzinc reagents that permits the rapid assembly of complex molecules through the formation of two alkyl–alkyl bonds. Alkylation is a chemical reaction that entails transfer of an alkyl group. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion, or a carbene (or their equivalents). Alkylating agents are reagents for effecting alkylation. Alkyl groups can also be removed in a process known as dealkylation. Alkylating agents are often classified according to their nucleophilic
