The new σ‐carbamoylnickel iodide 1 is superbly suited for formation of CC bonds. 1 had been postulated as an intermediate in nickel‐induced carbonylations, but never isolated. It exhibits high carbonylation activity in the reaction with CO and Et 2 NH to give the oxalic acid derivative 2 . The NiC σ‐bond in 1 is capable of undergoing addition to CC multiple bond systems; the allyl complex 3 is formed from 1 and allene.
