✦ Synopsis

Abstract

A new and efficient method for the synthesis of benzylphosphonate and benzylphosphonothioate diesters (including nucleosides), involves a palladium(0)‐catalyzed cross‐coupling between benzyl halides and H‐phosphonate or H‐phosphonothioate diesters using Pd~2~(dba)~3~(CHCl~3~) as a palladium source and Xantphos as a supporting ligand.
