A nickel-catalyzed reductive decyanation of aromatic nitriles has been developed, in which the readily available and abundant ethanol was applied as the hydride donor. Various functional groups on the aromatic rings, such as alkoxyl, amino, imino and amide, were compatible in this catalytic protocol. Heteroaryl, benzylic and alkenyl nitriles were also tolerated. Mechanistic investigation indicated
已经开发出镍催化的芳香腈的还原性脱氰,其中易得且丰富的乙醇用作氢化物供体。在该催化方案中,芳环上的各种官能团如烷氧基,氨基,亚氨基和酰胺是相容的。杂芳基,苄基和烯基腈也可耐受。机理研究表明,在该还原性脱氰反应中,乙醇通过消除β-氢化物有效地提供了氢化物。
