Vanadium Bromoperoxidases Mimicking Systems: Bromohydrins Formation as Evidence of the Occurance of a Hypobromite-Like Vanadium Complex.

In the aqueous phase of a two-phase (H2O-CH2Cl2) system mimicking the hydrophilic and the hydrophobic portions of vanadium dependent bromoperoxidases, (V-BrPO), a mono peroxovanadium complex, formed in situ by addition of H2O2 to NH4VO3, oxidizes Br(-) to a species whose nature is still largely unknown.Such species displays a bromine-like reactivity toward organic substrates dissolved in CH2Cl2.The observation that styrene, 1-methyl- and 2-methyl styrenes afford, together with dibromo-compounds, appreciable amounts of bromohydrins, suggests that a hypobromite-like species also formed.Evidence is presented that such a species is a vanadium complex.

Oxidation by DMSO. II. An efficient synthesis of α,β-diketones from α,β-dibromides

α,β-Dibromides refluxed in DMSO are oxidised into α,β-diketones. The reaction takes place rapidly under microwave irradiation.

Neighbouring group participation in the solvolysis of a class of heterocyclic and acyclic trans-dibromides and bromohydrins

Solvolysis of heterocyclic trans-dibromides and bromohydrins 1a-e affords the ring contracted aldehydes 10a-c and the benzthiophen derivative 11.The acyclic dibromide 2a similarly provides the expected aldehyde 13.Probable pathways for the formation of the products have been presented.

Elimination Reactions of Stilbene Dibromides. Dehydrobromination by Acetate, Cyanide or Chloride Ions in Dimethylformamide

Rates of dehydrobromination of a series of 4-nitro- and methoxystilbene dibromides by means of acetate, cyanide or chloride ions in dimethylformamide have been measured.A product analysis was performed which indicated a strong preference for anti elimination.Probable transition state structures utilized by each of the three nucleophiles are described.Attack by the base may be at either β-hydrogen (E 2H) or Cα(E2C).The slowest reaction in with chloride ion, which also gives the highest anti/syn elimination product ratio.
