The ruthenium-catalyzed oxidative vinylation of thiophene-2-carboxylic acids with alkenes efficiently proceeds through directed C−H bond cleavage to give the corresponding 3-vinylated products. Similarly, benzothiophene-, benzofuran-, pyrrole-, and indolecarboxylic acids also undergo regioselective vinylation.
噻吩-2-羧酸与烯烃的钌催化氧化乙烯基化可通过定向C-H键断裂而有效地进行,从而得到相应的3-乙烯基化产物。类似地,苯并噻吩-,苯并呋喃-,吡咯-和吲哚羧酸也经历区域选择性乙烯基化。
