A highly regioselective C–C bond cleavage of the cyclopropane rings occurs in substituted allenylcyclopropanes in the presence of cationic rhodium( I ) complexes. Thus, ring expansion of readily accessible allenylcyclopropanes can be achieved to give 3‐methylenecyclopentenes, which could have applications as multifunctional synthetic building blocks.
