Chemical Reactions of Coumarins and Furocoumarins on Thin-Layer Chromatoplates

Most of the reaction achieved in this work were conducted with coumarin and furocoumarin. The reactions were performed on inert thin-layer chromatoplates under controlled conditions and the products of the reactions were compared as usual with the expected substances on the same chromatogram. The reactions performed were: mineral acid hydrolysis, methylation, acetylation, benzoylation, nitration and Schiff's bases on silica gel chromatoplates.
