One-pot Synthesis of Stable Phosphite Ylides by three component reaction between Acetylenic Esters,Aldehyde Semicarbazones and Tributyl or Triethyl Phosphite

Abstract

Three-component reaction between acetylenic esters, aldehyde semicarbazones and tributyl- or triethyl phosphite leads to stable crystalline phosphite ylides at one step in nearly quantitative yields.

Keywords

acetylenic esters semicarbazones phosphite ylides tributyl phosphite triethyl phosphite
