Disclosed is a process for preparation of difluoro-tetraiodobenzene comprising contacting difluorobenzene with molecular iodine in the presence of fuming sulfuric acid.

Process for preparation of difluoro-tetraiodobenzene

A process for preparing a polymer having repeating units corresponding to the structure ##STR1## wherein R is ##STR2## y is in the range of 0.005 to 0.10, x is in the range of 0.01 to 0.50 when R is ##STR3## x is in the range of 0.01 to 0.30 when R is ##STR4## and n is at least 200. The polymer is prepared by reacting a diiodoaromatic compound and elemental sulfur.

Copoly(phenylene sulfide)

A process for iodinating aromatic compounds by reacting an aromatic compound with oxygen at low temperatures in the presence of a non-acid catalyst containing an oxidation catalyst. The catalyst may be regenerated by heating the catalyst in the presence of oxygen.
