The sequence of events leading to dihalide desorption and the role of vacancies will be described.
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.
