Formation of 4-hydroxy-5-[aryl(alkyl)-1H-pyrazol-4-yl]benzene-1,2-dicarbonitriles in reactions of benzofurans with hydrazines
摘要:
Some regularities are discussed of the reaction between 3-substituted benzofuran-5,6-dicarbonitriles with hydrazines leading to the formation of new 4-hydroxy-5-[aryl(alkyl)-1H-pyrazol-4-yl]-benzene-1,2-dicarbonitriles.
