Abstract

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.

Graphical Abstract

The new series of heteroatom substituted 1,4-naphtho- and 1,4-benzoquinone compounds were synthesized via vinylic substitution. Photo- and electrochemical properties of N-, S-, O-substituted quinone compounds were investigated by fluorescence spectroscopy and cyclic voltammetry. The structure of 2-(7-sulfanyl-4-methyl-coumarinyl)-3-(1-ethoxy)-1,4-naphthoquinone 13 was determined by X-ray diffraction method.
