MERCURY(II) BROMIDE (7789-47-1) Light and heat cause decomposition. Aqueous solution is acidic. Incompatible with indium (violent at 662°F/350°C), potassium, sodium. 

The procedure described below for the preparation of indium(I) bromide is extremely simple. Moreover, by appropriate variation of the stoichiometry of the reactants, it can be used for the preparation of indium dibromide. The preparation consists of the reaction of indium metal with mercury(II) bromide at an elevated temperature in a sealed evacuated tube. Mercury (I) bromide can be used in place of the mercury(II) compound. The same method can also be used for the synthesis of the chlorides and iodides of lower-valent indium. ... 

The reaction is carried out in a 20 X 0.8-cm. piece of thick-walled Pyrex tubing which has a small well of 8-mm. tubing sealed about 6 cm. from the closed end of the tube. One and fifteen-hundredths grams (0.01 mol) of indiumf and 1.80 g. (0.005 mol) of mercury(II) bromide are weighed into the reaction tube. The tube is then evacuated to a pressure of 10 to 15/i, sealed, and heated to 350° in a muffle furnace for about 30 minutes. The mercury set free is separated from the molten indium (I) bromide by removing the tube from the furnace and carefully tilting it so that the mercury runs into the well. To ensure complete... 

Triethylsilane and trityl salts.or Trimethylsilyl Triftuoro-methanesulfonate are effective for the reduction of various ketones and acetals, as are combinations of Chlorotrimethylsi-lane and indium(III) chloride and Tin(II) Bromide and Acetyl Bromide. Isophthaldehyde undergoes reductive polycondensation to a polyether when treated with triethylsilane and Triphenyl-methyl Perchlorate. ... 

Although in this chapter we shall be restricting coverage to reactions of transition-metal complexes, the phenomenon of oxidative addition is not confined to this type of compound. Such reactions are also well established for non-transition metals—a recently reported example concerns the oxidative addition of methyl bromide to indium(i) bromide to give InBr2Me— and for non-metals, as in the reaction of phosphorus trichloride with chlorine, to cite a very familiar example. Likewise, reductive eliminations are known and studied outside the area of transition-metal complexes. One example has been mentioned in Chapter 1 of Part II of this volume, namely the elimination of alkyl halides from the thallium(iii) compounds TlRXa. ...
