摘要：

The reaction of carbmethoxymethylene (la)-, carbethoxymethylene (lb)-, acetylmethylene (Ic)-, and benzoylmethylene (Id)-triphenylphosphoranes with N, N'-2, 5-cyclohexadiene-l, 4-diylidenebis (methanesulfonamide) (IIa) and its 2-chloro-derivatives lib afforded the new ylid-phosphoranes IHa-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. © 1990, Taylor & Francis Group, LLC. All rights reserved.
