Visible–Light–Induced Phosphorylation Reaction of α‐Diazoesters with H‐Phosphine Oxides to Construct (Z)‐Phosphinic Hydrazones

Abstract

A convenient visible‐light‐promoted phosphorylation reaction of α‐diazoesters with H‐phosphine oxides for the preparation of (Z)‐phosphinic hydrazones has been explored. This reaction could be performed under mild conditions to afford a series of (Z)‐phosphinic hydrazones in moderate to good yields through photoisomerization of C=N bond.
