Neuartige synthetische Aspekte der Phosphonat-Phosphat-Umlagerung, 2. Mitt.: Synthese von Enolphosphaten aus 1-Oxoalkanphosphonaten und Schwefelyliden

摘要

Acylphosphonates1react with Sulfur-ylides2to give enolphosphates3and phosphonophosphates4. The product ratio of3and4is determined by the substituentR3. IfR3is not electronwithdrawing the phosphonophosphate4is the sole reaction product.
