(Represented Chemical Equation) 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.
