Giving direction: An C sp 3-H bond activation directed by a rhodacycle intermediate has been found to occur in a Rh(I)-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%).
在铑（I）催化的反应中，具有叔丁基取代基的丙二烯部分与连接的炔烃之间，发现通过一个钌环中间体可以使 Csp3-H 键活化。含有环丙烷环的环状化合物以良好至高的收率（高达 92%）获得。
