A general, efficient iron‐catalyzed α‐alkylation of nitriles with primary alcohols through a hydrogen‐borrowing pathway has been developed, allowing a wide variety of alkylated nitriles to be readily accessible. Detailed mechanistic studies suggest that the reaction proceeds via an olefin intermediate with the turnover rate limited by the hydrogenation of the olefin with an iron hydride. Apart from
已经开发了一种普遍的,通过氢借入途径与伯醇进行的高效铁催化的腈与伯醇的α-烷基化反应,使各种烷基化的腈均易于获得。详细的机理研究表明,反应是通过烯烃中间体进行的,其转化率受烯烃与氢化铁的氢化作用所限制。除了参与烷基化以外,还发现腈在促进活性催化物质的形成和稳定中起着重要作用。
