Giving direction : An C sp 3H 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%).
