Rh-catalyzed intermolecular hydroacylation between salicylaldehyde and alkenylnitriles proceeded at room temperature to preferentially give normal-hydroacylated products. Addition of CH3CN and NaOAc accelerated the Rh-catalyzed hydroacylation of monoolefins to exclusively produce the normal-hydroacylated products under mild reaction conditions. Plausible mechanisms for the regioselections are also
水杨醛和链烯腈之间的Rh催化的分子间加氢酰化反应在室温下进行,优先得到正加氢酰化的产物。在温和的反应条件下,CH 3 CN和NaOAc的加入加速了Rh催化的单烯烃加氢酰化反应,从而独家生产出正常的加氢酰化产物。还描述了可能的区域选择机制。
