The condensation of diphenic anhydride with o-, m- and p- halogenosubstituted phenylacetic acids gave the respective enolacetates Ia-Ie. The alkaline hydrolysis of these compounds yields the diketones IIa-IIe. After testing blood cloting agents in vivo, the last compounds showed indications of anticoagulants.
