A direct cyanation of benzyl ethers and 1,3‐diarylpropenes with TMSCN was performed under solvent‐ and metal‐free conditions. This oxidative cross dehydrative coupling (CDC) reaction was promoted by 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) and provided rapid access to a broad range of nitriles in good to excellent yields.
在无溶剂和无金属的条件下,用TMSCN对苄基醚和1,3-二芳基丙烯进行直接氰化。2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)促进了这种氧化交叉脱水偶联(CDC)反应,并提供了以良好或优异的收率快速获得各种腈的途径。
