nickel‐catalyzed α‐allylation of aldehydes with allyl alcohol is reported. The reaction is promoted by 1 mol % of in situ formed nickel complex in methanol, and water is the sole by‐product of the reaction. The experimental conditions allow the conversion of various α‐branched aldehydes and α,β‐unsaturated aldehydes as nucleophiles. The same catalyst and reaction conditions enabled a tandem aldol condensation
据报道,醛与烯丙醇的无镍镍催化α-烯丙基化反应。1摩尔%的原位形成的镍络合物在甲醇中促进了反应,而水是反应的唯一副产物。实验条件允许各种α-支链醛和α,β-不饱和醛转化为亲核试剂。相同的催化剂和反应条件可实现醛/α-烯丙基化反应的串联羟醛缩合反应。
