Pd-mediated C-H arylation of EDOT and synthesis of push-pull systems incorporating EDOT

The direct C-H arylation of 3,4-ethylenedioxythiophene (EDOT) is described under Heck-type experimental conditions. This methodology has been used to synthesize a series of push-pull systems containing EDOT units. (C) 2007 Elsevier Ltd. All rights reserved.
