Abstract:

New fluorinated 2-arylhydrazones of 1,2,3-triketones, 2-arylhydrazone-1,2,3-diketo esters and 3-arylhydrazone-1,2,3,4-triketo esters have been prepared by the coupling of fluorine-containing 1,3-keto esters, 1,3-diketones, acyl(aroyl)pyruvic esters and their chelates with aryldiazonium chlorides. The arylhydrazones react with hydrazine hydrate, phenylhydrazine, thiosemicarbazide and hydroxylamine to form the corresponding pyrazole and isoxazole derivatives. Interaction of 3-arylhydrazone-1,2,3,4-diketo esters with o-phenylenediamine results in quinoxaline products. Intramolecular cyclization of the arylhydrazones with pentafluorophenyl substituents leads to cinnolone derivatives. (C) 1998 Published by Elsevier Science S.A.
