The (perfluoroalkyl)- and (perfluorooxaalkyl)diazines, 2,4-bis(perfluorooctyI)pyrimidine (3), 2,4,6-tris(perfluorooctyl)pyrimidine (6a), 2,4,6-tris(perpuoro-6-methyl-5-oxaheptyl)pyrimidine (66), 3,6-bis(perfluorooctyl)pyridiazine (10) and 2,6-bis(perfluorooctyl)pyrazine (13), have been prepared in good yield. This was accomplished by using chloro-substituted diazines as substrates in copper-mediated cross-coupling reactions with perfluoroalkyl and perfluorooxaalkyl iodides. The yields of the cross-coupled products are influenced by the reaction conditions as well as by the structure of the fluoroaliphatic iodides and substrates.

aldehyde, followed by oxidation of the resulting alcohol to the ketone, which in turn has been treated with sulphur tetrafluoride. Some nucleophilic substitution reactions of these compounds and perfluoro-n-propylbenzene are described. The possibility of the use of some of the products as surfactants is discussed.
