Synthesis of 4,6-Bis(4',5'-dihydro-5'-arylpyrazol-3'-yl)resorcinols as Potential Antifeedants.-2,4-Dihydroxy-5-acetylacetophenone (I) is coupled with aromatic aldehydes (II) to yield the corresponding dichalcones (III) which undergo cyclization with hydrazine hydrate (IV) to give the bis( dihydropyrazolyl)resorcinols (V). Two of these compounds show high antifeedant activity. -(RAJANI, P.; ASHOK, D.; SARMA, P. N.; J. Indian Chem. Soc. 67 (1990) 10, 854-855;
