Abstract
A process for preparing 4- atsetylfenilzamischenyh heterocyclic compounds, heterocyclic compounds in which arylyuyut arendiazoniyevymy salts in the presence of a catalyst - SuSl2 • 2H2O in water-acetone medium for 2-3 hours. at room temperature. As arendiazoniyevu salt using 4- atsetylfenildiazoniyu chloride, as well as heterocyclic compounds using coumarin, 3-hidroksykumaryn, 1 methylquinoline -2-furfural or online and receive 4 atsetylfenilzamischeni heterocyclic compounds.
