Facile Preparation of Vinyl S -Trifluoromethyl N H Aryl Sulfoximines
Résumé
We report herein the preparation of ortho-vinylaryl S-trifluoromethylated sulfoximines through cross-coupling reactions. Two efficient palladium-catalyzed procedures (Stille and Suzuki) were developed, with use of ortho-iodo aryl sulfox-imines as substrates, to give various vinyl derivatives in good yields. The difference in reactivity of the fluorinated derivatives,
