Electrolysis of phenylacetonitriles in methanol in an undivided cell in the presence of sodium halides as mediators induces a stereoselective oxidative coupling process that results in the formation of trans-α,β-dicyanostilbenes in 60–85 % yield with 40–70 % current efficiency. The application of this efficient stereoselective electrocatalytic method to the formation of trans-α,β-dicyanostilbenes represents
在存在卤化钠作为介质的情况下,在未分隔的电池中,苯乙腈在甲醇中的电解诱导立体选择性氧化偶联过程,导致反式-α,β-二氰基芪的形成,产率为 60-85%,电流效率为 40-70%。将这种高效的立体选择性电催化方法应用于反式-α,β-二氰芪的形成代表了一种环境友好的合成策略,从大规模工艺的角度来看是有价值的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451德国魏因海姆,2007)
