El’tsov, A. V.; Sokolova, N. B.; Grigor’ev, A. D.; Dmitrieva, N. M.; Shtol’vin, A. S. published the artcile< Synthesis of Quinizarin and Its Derivatives under Conditions of Microwave Activation>, Application In Synthesis of 118-45-6, the main research area is microwave quinizarin preparation; anthracenedione dihydroxy microwave quinizarin preparation; isoindoledione chlorophenol microwave quinizarin preparation; cyclocondensation phthalic anhydride chlorophenol microwave quinizarin preparation.
In a microwave field, phthalic anhydride reacts with p-chlorophenol to give 1,4-dihydroxyanthraquinone (quinizarin) within 10 min. The reaction with 4-chlorophthalic anhydride occurs similarly. Phthalic and chlorophthalic acids can be used instead of anhydrides. 3-Nitrophthalic acid and 3,4,5,6-tetrabromophthalic anhydride do not react with p-chlorophenol under these conditions.
Russian Journal of General Chemistry (Translation of Zhurnal Obshchei Khimii) published new progress about Cyclocondensation reaction. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Application In Synthesis of 118-45-6.
