The phosphorylation of organic compounds by phosphoric anhydride. Part 3. Synthesis of monosubstituted ketenes in the reaction of esters with phosphoric anhydride and cyclotrimerization of these ketenes

Monosubstituted ketenes 1 have been synthesized from substituted acetic esters 2 by elimination of alcohol under the action of phosphoric anhydride. The ketenes undergo cyclotrimerization to give substituted phloroglucinols (1,3,5-trihydroxybenzenes)3 and their phosphorylated derivatives.
