Abstract
Treatment of the salt generated from 2,4,4,6-tetrabromo-2,5-cyclohexadienone and PPh 3 in a mixed solvent of CH 3 CN toluene with primary and secondary alcohols in the presence of Zn(N 3) 2·2Py led to azides in excellent yields with inversion of configuration. Addition of hexamethylphosphorictriamide considerably accelerated the reaction.
