Popis:	A novel ketenimine Pauson-Khand reaction has been described for the first time. C,C,N-Triarylketenimines reacted with alkyne-dicobalthexacarbonyl complexes upon heating in toluene in the presence of dimethyl sulfoxide as a promoter to afford γ-lactams, 5-(diphenylmethylene)-1H-pyrrol-2(5H)-ones, in good yields.
