The Cu2O-catalyzed reaction of α,β-unsaturated isonitrile with active methylene compound is described. Vinyl isocyanide (VIC) and propenyl isocyanide (PPIC) were employed as the isocyanide components. In addition, allyl isocyanide (AIC), which has been known to be rearranged readily to PPIC by Cu2O, was also used as a precursor of PPIC. Five types of products were isolated and identified. These products
描述了 α,β-不饱和异腈与活性亚甲基化合物在 Cu2O 催化下的反应。使用乙烯基异氰化物(VIC)和丙烯基异氰化物(PPIC)作为异氰化物组分。此外,已知容易被 Cu2O 重排为 PPIC 的烯丙基异氰化物 (AIC) 也被用作 PPIC 的前体。五种类型的产品被分离和鉴定。这些产品由从活性亚甲基化合物衍生的有机铜-异腈络合物 (9) 中间体开始的方案进行解释。
