Oxidative Coupling of CH-acid Compounds with p-Phenylene Diamines. III. Reactivity of 4-Substituted 3-Methyl-1-phenyl-pyrazolin-5-ones with N,N-Diethyl-quinone-(1,4)-diimineSubstitution products 2-28 of 3-methyl-1-phenyl-pyrazolin-5-one 1, with a wide variety of substituents in the 4-position, were synthesized. Most of these compounds react with N,N-diethyl-quinone-(1,4)-diimine by elimination of the substituent giving the same azomethine dye as that formed by oxidative coupling of the 4-unsubstituted compound. A study of the influence of side reactions by measurement of dye yields has been undertaken.
