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

Abstract

AbstractA 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.
