(Z)-Sodium enolates of two alpha-azido ketones are O-formylated with Me3CCO2-CHO in high yield to give isolable (Z)-beta-(formyloxy)vinyl azides, which are converted to 1,2,3-triazoles under the influence of triethyl phosphite. A mechanism is proposed for triazole formation involving 1,5-electrocyclization of a vinyl phosphazide intermediate.
