SYNTHESIS AND PROPERTIES OF o-QUINONE DIAZIDES. PHOTOLYSIS OF 3-(p-TOLYLCARBAMOYL)-1,2-NAPHTHOQUINONE 1-DIAZIDE
The photochemical decomposition of 3-(p-tolylcarbamoyl)-1,2-naphthoquinone 1-diazide in aqueous or alcohol solutions of dioxane or tetrahydrofuran leads to high yields of indenecarboxylic acid or its esters.Whereas indenecarboxylic acid exists exclusively in the form of the 3-isomer, the methyl and ethyl esters form a tautomeric mixtures (approximately 1:1.5) of the 1- and 3-isomers.The ratio of the isomeric esters does not depend significantly on temperature (20-50 deg C) or on the polarity and acid-base characteristics of the solvent.
