A convenient and efficient palladium-catalyzed synthesis of aromatic ketones and isoindolobenzimidazoles has been developed via selective aromatic CH bond acylation. The protocol uses palladium acetate as the catalyst, readily available carboxylic acids as the acylating reagents, trifluoroacetic anhydride as the activated agent of the acids, and the corresponding aromatic ketones and isoindolobenzimidazoles
通过选择性芳族CH键的酰化反应,已经开发了一种便捷高效的钯催化芳族酮和异吲哚并苯并咪唑类化合物的合成方法。该方案使用乙酸钯作为催化剂,容易获得的羧酸作为酰化剂,三氟乙酸酐作为酸的活化剂,并以良好或优异的收率获得了相应的芳族酮和异吲哚并苯并咪唑。该发现应为合成芳族酮和异吲哚并苯并咪唑类化合物提供一种新的有用的策略。
