The reactions of 4-methyl-7-diethylaminocoumarin with various electrophilic reagents - acetic anhydride, complexes of unsaturated compounds (styrene, dihydropyran, phenylacetylene) with Lewis acids, and copper halides - were used to synthetize 3-, 6-, and 8-substituted coumarins.It was shown that the selectivity of reactions involving substitution in the 3 position increases with an increase in the "softness" of the Lewis acid.
