Diethyl benzoylphosphonate (1) underwent facile benzoylation of alcohols in the presence of DBU. Reactions of diols containing primary and secondary hydroxyl groups with 1 gave predominantly monobenzoates in which primary hydroxyl groups were highly selectively benzoylated. Related acylations were also described.
