Poly(arylene ether)s (PAE) are generally synthesized via nucleophilic aromatic substitution of an activated dihalide with an aromatic bisphenol (2-7).
Similar conditions were used as described in the synthesis of poly(arylene ether methyl phosphine oxide sulfone) - the only exception being that 4,4[prime]-bis(fluorophenyl)phenylphosphine oxide (BFPPO) was used at the activated dihalide instead of methyl analog (BFPMPO).
Nitration at ortho position to the ring's halo group(s), hereto referred as selective ortho-nitration, has been anything but selective and literature has no record of examples of adjacent dinitration of aryl dihalides.
