THE PHOSPHORYLATION OF ORGANIC-COMPOUNDS BY PHOSPHORIC ANHYDRIDE .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.
