Synthese und Redoxverhalten schwefelsubstituierter Naphthochinone-1,4 / Synthesis and Redox Behaviour of Sulfur Substituted Naphthoquinones-1,4

Abstract

Abstract Chloro substituted naphthoquinones-1,4 1 react with di-Na-4,5-dithio-1,3-dithiol-2-thiones 2 and other dithiolates to give new sulfur containing heterocyclic quinones 3 and 4 as possible preliminary states to synthesize tetrathiafulvalenes. The reaction of 1 with di-Li-2,2- bis(methylthio)-1,1-ethylendithiol 8 yields the appropriate bis-(methylthio)methylen substituted naphthoquinones 9. The redox behaviour of the new compounds was investigated by cyclic voltammetry
