Methods for the direct synthesis of difluoromethylated arenes are sparse, despite the importance of the difluoromethyl group in medical, agro‐, and materials chemistry. A palladium‐catalyzed decarbonylative cross‐coupling reaction of acid chlorides with a difluoromethyl zinc reagent is achieved to access difluoromethylated compounds. The transformation proceeds at room temperature and shows broad functional
尽管二氟甲基在医学,农业和材料化学中很重要,但直接合成二氟甲基化的芳烃的方法很少。酰基氯与二氟甲基锌试剂的钯催化脱羰交叉偶联反应可实现二氟甲基化化合物的访问。该转化在室温下进行并显示出宽泛的官能团耐受性,因此提供了用于广泛范围的芳族羧酸的脱羰二氟甲基化的通用且有效的方法。
