Abstract

A new straightforward synthesis of isomerically pure anthra [2, 3-b: 6, 7-b′]-difuran (anti- ADF),-dithiophene (anti-ADT), and-diselenophene (anti-ADS) from readily available 2, 6- dimethoxyanthracene is described. The present successful synthesis makes it possible to overview the linear-shaped anti-acenedichalcogenophene compounds, that is, benzo [1, 2- b: 4, 5-b′]-, naphtho [2, 3-b: 6, 7-b′]-, and anthra [2, 3-b: 6, 7-b′]-difuran,-dithiophene, ...
