Abstract
Various N-arylpyrazoles can be prepared by a condensation reaction fro m pyrazoles and activated aryl ethers as 2,4-dinitrophenyl phenyl ethe r and 2,4,6-trini-trophenyl-phenyl ether in DMSO as solvent at 155-165 degrees for 1-3 hours. The basicity of pyrazoles and the reactivity o f activated aryl ethers are important factors in this reactions.
