Abstract

PURPOSE: To prepare a phosphoric acid ester in an improved yield from a specific alcohol and phosphoric acid or its ester, by activating the alcohol instead of the phosphoric acid group.
CONSTITUTION: A phosphoric acid ester III is prepared by reacting phosphoric acid or its ester I (R1 and R2 are aryl, aralkyl, alkyl or H) with an alcohol II (R3 is aryl or an organic group, e.g. alkyl, etc., which may be substituted with alkoxy, acetylene, saturated or unsaturated fatty acid residue, phenylthioalkayloxy, etc.). The compound I is prepared in an improved yield by carrying out the reaction with activating the alcohol instead of the phosphoric acid group.
