Other Metal Halides

In addition to the alkali and alkaline earth ions the chloride, bromide and iodide ion relaxation has also been investigated in the presence of the following metal ions  

With many of the metal ions listed above, there is an exchange of halide ions between being free in solution and being more or less 

Hertz [237] noted that the Br relaxation rate is doubled, compared to the infinite dilution value, at about 1 M for aqueous AlBr solutions. The corresponding figure for alkaline earth bromides is 

As a result of the very rapid halogen relaxation in covalent metal ion-halide complexes, addition of quite small amounts of halidecoordinating metal ions may be sufficient to cause appreciable halogen 

Garnett and Halstead [301] used Br NMR to investigate the relative affinities of some anions in binding to three organomercu-

When arylhydrazones of aldehydes or ketones are treated with a catalyst, elimination of ammonia takes place and an indole is formed, in the Fischer indole synthesis,Zinc chloride is the catalyst most frequently employed, but dozens of others, including other metal halides, proton and Lewis acids, and certain transition metals have also been used. Microwave irradiation has been used to facilitate this reaction. Aniline derivatives react with a-diazoketones, in the presence of a... 

It reacts even more vigorously with most substances than does cobalt fluoride. See other metal halides, silver compounds...
