The reaction of carbmethoxymethylene (Ia)-, carbethoxymethylene (Ib)-, acetylmethylene (Ic)-, and benzoylmethylene (Id)-triphenylphosphoranes with N,N'-2,5-cyclohexadiene-1,4-diylidene-bis(methanesulfonamide) (IIa) and its 2-chloro-derivatives IIb afforded the new ylid-phosphoranes IIIa-g via 1,2-addition reaction.Structural reasoning for compounds III was based on compatible analytical and spectral data (IR, 1H-NMR, 31P-NMR, 13C-NMR, and MS).The mechanism that accounts for formation of adducts III is discussed.
