Aplicação

Zinc bromide supported on silica or montmorillonite can be used as a selective catalyst for the bromination of aromatic substrates.

It can be used as starting material to prepare poly(ethylene oxide)/ zinc salt systems, which can be used as polymer electrolytes.

Itcan also be used to prepare ZnO nanoparticles.

The transthyretin-related protein (TRP) family comprises proteins predicted to be structurally related to the homotetrameric transport protein transthyretin (TTR). The function of TRPs is not yet fully established, but recent data suggest that they are involved in purine catabolism. We

The alpha,alpha-gem-difluorination of 2',4'-difluoro-alpha-(methylthio)acetophenone (1a) with N-fluoropyridinium salts gave 2',4',alpha,alpha-tetrafluoro-alpha-(methylthio)acetophenone (3a). This reaction was accelerated by the addition of zinc chloride, zinc bromide or anhydrous iron(III) chloride, and higher yields than the reaction without additives were obtained. The gem-difluorination reaction
