A new and general nickel-catalyzed cyanation of hetero(aryl) chlorides using less toxic Zn(CN)2 as the cyanidesource has been developed. The reaction relies on the use of inexpensive NiCl2·6H2O/dppf/Zn as the catalytic system and DMAP as the additive, allowing the cyanation to occur under mild reaction conditions (50–80 °C) with wide functional group tolerance. DMAP was found to be crucial for successful
已经开发了一种新的且一般的镍催化的杂(芳基)氯化物氰化方法,该方法使用毒性较小的Zn(CN)2作为氰化物源。该反应依赖于使用廉价的NiCl 2 ·6H 2 O / dppf / Zn作为催化体系,并使用DMAP作为添加剂,从而使氰化反应在温和的反应条件下(50–80°C)发生,且具有宽泛的官能团耐受性。发现DMAP对于成功转化至关重要,并且基于机理研究,该反应可能通过Ni(0)/ Ni(II)催化进行。该方法也成功地扩展到了芳基溴化物和芳基碘化物。
