A satisfactory method for the preparation of nickel tetracarbonyl. Nevertheless, if a nickel salt is introduced, it is possible to observe a longer or shorter induction period and it may therefore be preferable to use compounds of nickel zero, such as nickel tetracarbonyl and bis-(triphenylphosphine)-nickel dicarbonyl.
