| titleOfInvention | Novel Method for Preparing 4-hydroxy-3-sulfanylcoumarin Derivatives or 4-hydroxy-3-sulfanylquinoline Derivatives and Their Compounds Made Thereby, and Its Use |
| abstract | The present invention relates to a 4-hydroxy-3-sulfanylcoumarin derivative represented by the following formula (1) and a 4-hydroxy-3-sulfanylquinolinone derivative represented by the following formula According to the production method of the present invention, the production cost can be reduced by using an inexpensive catalyst and a desired product can be obtained at a high yield, so that the reaction efficiency is excellent, and the derivative Can be used as a composition for detecting cadmium in water since they exhibit activity to detect cadmium in water; [Chemical Formula 1] Wherein R 1 is selected from the group consisting of hydrogen, (C 1 -C 4) alkyl and halogen, R 2 and R 3 are each independently selected from hydrogen or halogen, and R 4 is a substituted or unsubstituted phenyl group , A substituted naphthyl group and an unsubstituted thienyl group, and the substituted phenyl group is one in which one to three hydrogens of the benzene ring are substituted with a (C1-C4) alkyl group, and the substituted naphthyl group is Di (C1-C4 alkyl) amine group; (2) Wherein R 5 is any one selected from the group consisting of hydrogen, (C 1 -C 4) alkyl and halogen, R 6 is (C 1 -C 4) alkyl or hydrogen, and R 7 is a substituted or unsubstituted phenyl group And substituted naphthyl groups, wherein the substituted phenyl group is one in which one to three hydrogens of the benzene ring are substituted with (C1-C4) alkyl groups, and the substituted naphthyl group is selected from the group consisting of di To C4 alkyl) amine groups. |
