Novel Synthetic Aspects of the Phosphonate-Phosphate-Rearrangement. II. Synthesis of Enolphosphates from 1-Oxoalkanphosphonates and Sulfur-Ylides

Article abstract of DOI:10.1007/BF00909658

Acylphosphonates 1 react with Sulfur-ylides 2 to give enolphosphates 3 and phosphonophosphates 4.The product ratio of 3 and 4 is determined by the substituent R³.If R³ is not electronwithdrawing the phosphonophosphate 4 is the sole reaction product. - Keywords: Acylphosphonates, behaviour towards S-ylides; Rearrangement of α-hydroxyphosphonates
