Ylide compounds alkene-conjugated ylides

Electrophilic nitrogen compounds, such as arenesulfonyloxyamines, can convert alkenes to aziridines without the intervention of free nitrenes (80CC560). The ylide Ph2S+-NH adds stereospecifically to E and Z conjugated alkenes, and chiral sulfimides can transfer chirality to the aziridines formed (80T73). These reactions are often named aziridinations . [Pg.512]

Vinylsulfonium salts serve as an electron-deficient alkene and conjugate addition to the alkene generates sulfonium ylides. Thus, conjugate addition to vinylsulfonium compounds provides another preparation of cyclopropanes. For... [Pg.8]
