Abstract: Interactions of 6-coumarinyldiazonium chloride with styrene, acrylonitrile, metylmetacrylate were investigated. The products of chloroarylation with acrylonitrile – 2-chloro-3-(2-oxo-2H-6-chromenyl)propanenitrile, metylmetacrylate – methyl 2-chloro-2-methyl-3-(2-oxo-2H-6-chromenyl)propanoate and 6-(2-phenyl-1-ethenyl)-2H-2-chromenone with styrene in catalytic conditions by copper (II) salts were obtained.
Keywords: 6-aminocoumarin; 6-diazocoumarinyldiazonium chloride; chloroarylation
