Giving direction: An CH bond activation directed by a rhodacycle intermediate has been found to occur in a RhI‐catalyzed reaction between an allene moiety having a tert‐butyl substituent, and tethered alkynes. Cyclic compounds containing a cyclopropane ring were obtained in good to high yields (up to 92%).
给方向:一个Ç H键活化中间体rhodacycle定向已经发现在铑发生我催化的具有丙二烯基团之间的反应叔丁基取代基,并且拴系炔烃。以良好至高的收率(高达92%)获得了含有环丙烷环的环化合物。
