- Synthesis, characterization of N-, S-, O-substituted naphthoand benzoquinones and a structural study
-
The new series of N-, S-, O-substituted 1,4-naphthoquinone and S-, O-substituted 1,4- benzoquinone compounds were synthesized via vinylic substitution. Compounds 3 and 4 were synthesized from the reaction of 1 with 2. Compounds 6, 7 and 8 were synthesized from reaction of 1 with 5. Compounds 10 and 11 were obtained from the reaction of 1 with 9. Compounds 13 and 14 were synthesized from the reaction of 1 with 12. Compounds 16 and 17 were obtained from the reaction of 15 with 2. Photochemical and electrochemical properties of N-, S-, O-substituted quninone compounds were determined by using fluorescence spectroscopy and cyclic voltammetry. Crystal structure of 2-(7-sulphanyl-4- methyl-coumarinyl)-3-(1-ethoxy)- 1,4-naphthoquinone 13 was determined by X-ray diffraction method. Indian Academy of Sciences.
