The iron-catalyzed cross-dehydrogenative coupling (CDC) of C(sp3)–H/C(sp3)–H bonds to afford olefins by 4H elimination is described. This method employs air (molecular oxygen) as an ideal oxidant, and is performed under mild, ligand-free and base-free conditions. H2O is the only byproduct. Good tolerance of functional groups and high yields have also been achieved. Preliminary mechanistic investigations
描述了
铁催化的C(sp 3)–H / C(sp 3)–H键的交叉脱氢偶联(CDC),可通过4H消除得到烯烃。该方法使用空气(分子氧)作为理想的氧化剂,并且在温和,无
配体和无碱的条件下进行。H 2 O是唯一的副产物。还获得了对官能团的良好耐受性和高产率。初步的机械研究表明,目前的转变涉及一个根本过程。
