SYNTHESIS AND SPECTRAL-LUMINESCENCE PROPERTIES OF AZOMETHINES IN THE COUMRIN SERIES

Nitration of 7-diethylamino-4-methylcoumarin and reduction of the resulting 3-nitro-derivative gave 7-diethylamino-3-amino-4-methylcoumarin.A series of azomethines have been synthesized based on this material.The spectral-luminescence properties of the pr

REACTIONS OF 4-METHYL-7-DIETHYLAMINOCOUMARIN THAT PROCEED WITH ELECTRON TRANSFER

The reactions of 4-methyl-7-diethylaminocoumarin with various oxidizing agents, viz., nitrous acid, nitromethane in the presence of Lewis acids, tetranitromethane, lead tetraacetate, phenyliodosodiacetate, and p-benzoquinone, as well as with typical one-electron oxidizing agents +SbCl6-, NOBF4, NOSbCl6, (ClO4)3>, were studied.It was shown that most of the reactions can be interpreted as proceeding with the intermediate formation of the cation radical of the starting coumarin and lead to new substituted 7-aminocoumarins when suitable substrates (unsaturated compounds, radicals, etc.) are present.
