An efficient selective C(3)–H arylation of furan ring in 2-(furan-2-yl)benzimidazoles, derivatives of fuberidazole fungicide, with aryl bromides catalyzed by [RuCl2(cymene)]2/ pivalic acid system has been accomplished. High selectivity of the process may be accounted for by the action of benzimidazol-2-yl substituent as the directing group.
在[RuCl 2 (cymene)] 2 / 新戊酸体系催化芳基溴化物的2-(furan-2-yl)苯并咪唑衍生物中,呋喃环的高效选择性C(3)-H芳基化已经完成. 该方法的高选择性可以通过苯并咪唑-2-基取代基作为导向基团的作用来解释。
