Three new, surprising reactions of highly unsaturated hydrocarbons with [CpCo(C 2 H 4 ) 2 ] show once again the versatility of organometallic compounds. It catalyzes the rearrangement of [4]radialene 1 to 2 and the vinylation of the butatriene Me 2 CCCCMe 2 to give 3 ; finally, it metalates the “half‐radialene” 4 to give the η 4 ‐complex 5 .
