Giving direction: An CHbondactivation 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%).
