nickel-catalyzed cyanation of phenol derivatives with metal-free cyanating agents, aminoacetonitriles, is described. A nickel-based catalytic system consisting of a unique diphosphine ligand such as dcype or dcypt enables the cyanation of versatile phenol derivatives such as aryl carbamates and aryl pivalates. The use of aminoacetonitriles as a cyanating agent leads to an environmentally and easy-to-use method
由简单的芳族原料化学物质产生有用的芳腈结构代表了化学合成中的根本重要反应。描述了苯酚衍生物用无金属的氰化剂,氨基乙腈的第一次镍催化的氰化。由独特的二膦配体(例如dcype或dcypt)组成的镍基催化体系能够使通用的酚衍生物(例如氨基甲酸芳基酯和新戊酸芳基酯)氰化。氨基乙腈作为氰化剂的使用导致芳基腈合成的环境和易于使用的方法。
