A View [2+2+2] a Kill : For the first time, nickel‐catalyzed [2+2+2] cycloaddition reactions of alkynes or diynes with carboryne using 1‐iodo‐2‐lithiocarborane as a precursor have been achieved. The mechanism is proposed after the structural confirmation of the key intermediate, nickelacyclopentene.
