The palladium-catalyzed oxidative vinylation of indole-3-carboxylic acids with alkenes effectively proceeds via directed C-H functionalization and decarboxylation to produce the corresponding 2-vinylated indoles. Similarly, pyrrole-, furan-, and thiophenecarboxylic acids also undergo decarboxylative vinylation.
钯催化的吲哚-3-羧酸与烯烃的氧化乙烯基化反应可通过定向CH官能化和脱羧反应有效地进行,以生成相应的2-乙烯基化的吲哚。类似地,吡咯,呋喃和噻吩羧酸也经历脱羧乙烯基化。
