PHOTOCHEMICAL REACTIONS OF 7-AMINOCOUMARINS. 7. REACTION OF 3-IODO-4-METHYL-7-DIETHYLCOUMARIN WITH OLEFINS

Article abstract of DOI:10.1007/BF00480857

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, indene, ethyl β-anilinocrotonate, and 2,5-norbornadiene, as well as with phenylacetylene.Regiospecifity and stereospecifity of the investigated photoreactions were established.The spectral-luminescence characteristics of the synthesized compounds are presented.
