摘要:

The reaction of carbmethoxymethylene (1a)-, carbethoxymethylene (1b)-, acetylmethylene (1c)-, and benzoylmethylene (1d)-triphenylphosphoranes with N,N′-2,5-cyclohexadiene-1,4-diylidenebis (methanesulfonamide) (IIa) and its 2-chloro-derivatives IIb afforded the new ylid-phosphoranes IIIa-g via 1,2-addition reaction. Structural reasoning for compounds 111 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.
