Article abstract of DOI:10.1016/S0022-328X(00)99836-X

Diphenylacetylene and phenylisocyanate react with TMEDA/Ni⁰ to give an azanickela-5-ring (IVa) which yields the azanickela-7-ring (IIb) with an activated alkyne.It is shown that both IVa and IIb are intrmediates in the nickel-catalysed 2-pyridone synthesis.Pyrimidinediones are formed from diphenylacetylene and alkylisocyanates with TMEDA/Ni⁰.
