Cumulated Ylides, 22. - Reactions of (Triphenylphosphoranylidene)ethenone with Halogen Compounds and their Preparative Application

(Triphenylphosphoranylidene)ethenone (6) reacts with halogen compounds 7 to yield four-membered ylide phosphonium salts 9.Ring opening of 9 under different conditions gives rise to the formation of bis-ylides 13, ylide salts 14, or bis-phosphonium salts 1

The Chemistry of Vicinal Tricarbonyls. A New Synthesis of Substituted Furans.

Enolates of acyl phosphoranylidene carboxylates react with aldehydes to form secondary alcohols which undergo intramolecular addition to the central carbonyl of a vicinal tricarbonyl unit, generated in a separate step.The resulting dihydrofuranols undergo acid-catalyzed dehydration to form 3-hydroxyfuran-2-carboxylates.
