The development of an efficient and straightforward method for cyanation of alcohols is of great value. However, the cyanation of alcohols always requires toxic cyanide sources. Herein, an unprecedented synthetic application of an isonitrile as a safer cyanide source in B(C6F5)3-catalyzed direct cyanation of alcohols is reported. With this approach, a wide range of valuable α-aryl nitriles was synthesized
开发一种有效且直接的醇氰化方法具有重要价值。然而,醇的氰化总是需要有毒的氰化物源。在此,报道了异腈作为更安全的氰化物源在 B(C6F5)3 催化的醇直接氰化中前所未有的合成应用。通过这种方法,以良好到极好的收率(高达 98%)合成了多种有价值的 α-芳基腈。反应可以放大,这种方法的实用性在抗炎药萘普生的合成中得到进一步体现。此外,还进行了实验研究来说明反应机理。
