Abstract
A number of new 7-aminocoumarins having an unsaturated substituent in the 3 position were obtained as a result of photolysis of 3-iodo-4-methyl-7-diethylaminocoumarin with olefins, viz., styrene, acrylonitrile, methyl acrylate, methyl methacrylate, 4-vinylpyridine, 2-ethoxypropene, indent, ethyl Β-anilinocrotonate, and 2,5-norbornadiene, as well as with phenylacetylene. Regiospecificity and stereospecificity of the investigated photoreactions were established. The spectral-luminescence characteristics of the synthesized compounds are presented.
