A highly anti-Markovnikov selective oxidation of alkenes based on in situ generated hypoiodite catalysis in aqueous micellar media under mild conditions has been described. This novel catalytic system realizes an efficient synthesis of aldehydes from alkenes in an economically viable and environmentally safe fashion. The preliminary mechanistic studies suggest that the reaction proceeds via tandem iodofunctionalization/1,2-aryl or alkyl migration. The scope and limitations of this tandem process are demonstrated with various mono- and disubstituted (terminal and internal) olefins.

Oligomeric iodosylbenzene sulfate, (PhIO)3·SO 3, which can be formally considered as a partially depolymerized activated iodosylbenzene, is a readily available, stable, and water-soluble hypervalent iodine reagent that is useful for the oxidation of sulfides or alkenes. Furthermore, this reagent can be conveniently generated in situ from (diacetoxyiodo)benzene and sodium bisulfate and used without isolation in oxidations in aqueous solution or under solvent-free conditions. The reaction of iodosylbenzene sulfate in situ with organic sulfides at room temperature affords sulfoxides in high yields without over-oxidation to sulfones, and this reaction is compatible with the presence in the substrate molecule of hydroxy groups, double bonds, benzylic carbon atoms, carboxylate groups, and various substituted phenyl rings. The reaction of an alkene with iodosylbenzene sulfate generated in situ results in oxidative rearrangement to form a ketone or aldehyde. Georg Thieme Verlag Stuttgart.

Treatment of a thallium(I) carboxylate with 1 molar equivalent of bromine gives the corresponding thallium(III) carboxylate dibromide.High yields of primary alkyl bromides are obtained if the thallium(III) carboxylate dibromide is treated with 0.5 mol equiv. of bromine in refluxing carbon tetrachloride.Pyrolysis of the thallium(III) derivative in the absence of added bromine gives a low yield of the corresponding alkyl bromide.The use of thallium(I) carboxylates for the preparation of alkyl bromides in high yields is limited to the salts of primary carboxylic acids.A simple procedure for the preparation of alkyl bromides from carboxylic acids using thallium(I) carbonate has been developed.
