Fluoride

Very first, the reaction of 1-iodo-4-methoxybenzene with aniline-afforded N,N-bis(4-methoxyphenyl)benzenamine was performed. Second, α-diketone 1,2-bis(4-(bis(4-methoxyphenyl)amino)phenyl)ethane-1,2-dione was ready via the Friedel–Crafts reaction of 1 in the presence of oxalyl chloride26. Third, two reactions, i.e., zinc-mediated reduction and condensation, had been performed on 4,7-dibromothiadiazole derivatives to synthesize dibrominated quinoxaline monomers with powerful electron-withdrawing F and CN substituents . Lastly, the polymerization of a...
