XDOTs, EDXTs, EDOXs, and 2(5)-X(2)-EDOTs: Ring Size Variations, Heteroanalogs, and Derivatives of EDOT with Substituents at the Thiophene Ring

MDOT derivatives have been known since the pioneering work of Dallacker and Mues from the year 1975.1,2 The synthesis of MDOT-dicarboxylic acid follows the versatile route also useful for 3,4-ethylenedioxythiophene (EDOT), using bromochloromethane instead of 1,2-dihalogenoethanes (Figure 13.1).
