three-component solvent-tree cyanoaroylation of aldehydes usingpotassiumhexacyanoferrate(II) as an environmentally benign cyanidesource and triethylamine as a catalyst has been described. This method has advantages of not using strongly toxic cyanating agents and volatile organic solvents. In addition, the product was obtained in high yield using a simple workup procedure.
已经描述了一种使用六氰基高铁酸钾 (II) 作为环境友好的氰化物源和三乙胺作为催化剂的醛的一锅三组分溶剂树氰基芳酰化的有效方法。该方法具有不使用剧毒氰化剂和挥发性有机溶剂的优点。此外,使用简单的后处理程序以高产率获得了产物。
Construction of Functionalized α-Imino Ketones via Pd-Catalyzed C–H Addition to Nitriles/Aerobic Oxidation Sequences
Pd(II)-catalyzed addition of sp2 C–H to nitrile/aerobic oxidation sequences for the preparation of functionalized α-imino ketones is described in which readily available heteroarenes and O-acyl cyanohydrins were employed. Various functionalized targeted molecules can be prepared in good yields with high atom and step economy. Moreover, a broad substrate scope and the ready manipulation and availability
