Structure and solvatochromic properties of the azo coupling products of 2,3-dihydrofuro[3,2-c]cumarin-3-one

Abstract

The azo coupling reaction of 2,3 dihydrofuro[3,2 с] coumarin 3 one with the arene diazonium salts was studied. The dependence of the product composition on the structure of the diazo component was shown. The solvatochromic properties of the compounds obtained were studied.
