bonds through the Ni-catalyzed Suzuki–Miyauracross-coupling of phenols with arylboronicacids has been developed. This reaction proceeds through the in situ tosylation of phenols by using N,N-ditosylaniline as the sulfonylating reagent, which is highly active, markedly stable, and easily prepared. The scope with respect to the coupling partners – phenols and boronic acids – is broad, and sensitive functional
已经开发出一种通过苯酚与芳基硼酸的 Ni 催化 Suzuki-Miyaura 交叉偶联来构建两个不同 Cary-Caryl 键的有效方法。该反应以N,N-二甲苯磺酰苯胺为磺酰化试剂,通过苯酚的原位甲苯磺酰化反应进行,磺酰化试剂活性高、稳定性好、制备容易。偶联伙伴(酚类和硼酸)的范围很广,并且可以容忍敏感的官能团。酚类,尤其是那些含有未保护氨基的酚类,在传统的一锅法条件下通常存在偶联问题,也是该转化中可行的底物。
