The present invention provides a process for the preparation of organic bromides, by a radical bromodecarboxylation of carboxylic acids with a bromoisocyanurate.

The present invention is directed to methods for the preparation of (C.sub.nF.sub.2n+1)O-substituted arenes and heteroarenes and the direct perfluoralkoxy lation of arenes and heteroarenes with a (C.sub.nF.sub.2n+1)O-group, respectively. characterized in that a peroxide reagent according to the general formula (I): (C.sub.nF.sub.2n+1)2 (I) is fragmented in the presence of an electron transferring catalyst under (C.sub.nF.sub.2n+1)O-radical formation, and said (C.sub.nF.sub.2n+1)O-radical then substitutes a CH bond of an arene or heteroarene CH bond with a (C.sub.nF.sub.2n+1)O-group, wherein in the above formulae, n is an integer in the range from 1 to 4.

The invention relates to a method of producing a compound represented by the formula (a) by reacting a compound represented by the formula (c) with a halogenating agent in a non-aqueous system:

##STR00001##

wherein R.sup.1 is a fluoroalkyl group having 1 to 3 carbon atoms, R.sup.2 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R.sup.3 is an alkyl group having 1 to 6 carbon atoms, and X is a halogen atom.

Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.
