EDOT Glyoxylation and Functionalization
(A) Treatment of EDOT with oxalyl chloride and subsequent treatment with the desired nucleophile generates functional end-capped derivatives, which can then undergo bromination (route A). Alternatively, amide or ester coupling can be undertaken from a common intermediate 10 to give the desired monomers (route B).
(B) Functionalized brominated monomers synthesized.
