Reactions of Phosphonate Carbanions with Selenium or Sulfur in the Presence of Amines. Synthesis of Seleno- and Thioamides

Article abstract of DOI:10.1246/cl.1992.131

The reaction of phosphonate carbanions with elemental selenium in the presence of amines afforded the corresponding selenoamides in moderate yields.The reaction of these anions with sulfur also gave thioamides.These reactions might proceed through thio- or selenoaldehyde intermediates.
