Abstract

3-Substituted 7-dialkylaminocoumarins were synthesized as a result of the photoreaction of 7-diethylaminocoumarin, 4-trifluoromethyl-7-diethylaminocoumarin, 4-chloro-7-diethylaminocoumarin, 4-(N-morpholino)-7-diethylaminocoumarin, and coumarin-102 (2,3,6,7-tetrahydro-9-methyl-1H,5H,11H-[1]-benzopyrano[6,7,8-ij]quinolizin-11-one) with iodobenzene, 3,4-dimethoxyiodobenzene, isopropyl iodide, and ethyl α-bromoacetate. It was established that electron-acceptor and electron-donor substituents in the 4 position accelerate photosubstitution. The spectral-luminescence characteristics of the compounds obtained were investigated.
