We disclose the first catalytic domino reaction of α-(2-formylaryloxy)acetonitriles with arylboronic acids, yielding a range of 2-aroylbenzo[b]furans with yields of up to 93%. Ni(acac)2 serves as an effective dual catalyst. The protocol is also applicable to α-(2-acetylphenoxy)acetonitrile, giving rise to 3-methyl-2-aroylbenzo[b]furans. This domino process is efficient, additive-free, and compatible
我们公开了 α-(2-甲酰基芳氧基)乙腈与芳基硼酸的首次催化多米诺反应,产生一系列 2-芳酰基苯并[ b ]呋喃,产率高达 93%。Ni(acac) 2是一种有效的双催化剂。该方案也适用于 α-(2-乙酰基苯氧基)乙腈,产生 3-甲基-2-芳酰基苯并[ b ]呋喃。该多米诺骨牌工艺高效、无添加剂,并且与多种芳基硼酸相容,包括带有CF 3、NO 2、CN 和CO 2 Me 基团的芳基硼酸。机理研究强调了镍催化剂促进的双重活化。
