AlBr3, EtSH, 0°, 0.5-1 h, 73-78% yield. Aluminum bromide cleaves aryl and alkyl methyl ethers in high yield methyl esters are stable. 

In the two previous examples, the sucrose and santonic acid existed in solution as molecules, instead of dissociating to ions. The latter case requires the total molality of all ionic species. Calculate the total ionic molality of a solution of 50.0 grams of aluminum bromide (AlBr3) in 700 grams of water. Because the gram formula weight of AlBt3 is... 

Aluminum bromide AlBr3 is used as a catalyst and parallels AICI3 in this role. Strontium and magnesium bromides are used to a limited extent m phamiacentical applications. Ammonium bromide is nsed as a flame retardant in some paper and textile applications potassium bromide is used in photography. Phosphorus tribromidc PBr3 and silicon tetrabromide SiBi4 are nsed as intermediates and catalysts, notably in the production of phosphite esters. 

The answer is definitely no, because if we add a small amount of aluminum bromide, AlBr3, to a mixture of tetrachloroethene and bromine, addition does occur, although sluggishly ... 

Aluminum bromide ( >2/,). For the molecule AlBr3, a structure similar to that of Irimethylborane would be expected with 120° bond angles. Experimentally, however, it is found that aluminum bromide is a dimer, Al2Brf,. This is readily explainable as a result of the tendency to maximize the number of bonds formed since AUBr contains four bonds per aluminum atom. This is possible... 

Aluminum bromide, AlBr3, which is used to add bromine atoms to organic compounds, can be made by passing gaseous bromine over hot aluminum. 

The starting material, K[[10B]F4], is readily prepared by dissolving [10B](OH)3 in hydrofluoric acid, and neutralizing the solution with aqueous KOH4 or K2C03. Although any pure, freshly sublimed AlBr3s can be used in the preparation of [10B]Br3, it is advisable to synthesize aluminum bromide shortly before it is used. 

Part of the aluminum bromide deposits on the cooler parts of the flask, forming colorless crystals. The dropping rate is adjusted so that the AlBr3 vapor does not reach the coil of the reflux condenser. A pressure drop observed towards the end of the reaction can be readily equalized by slowly admitting nitrogen...

In chapter 2, we saw that benzene reacts with electrophilic reagents such as the bromonium ion [Br+, generated by the reaction of bromine (Br2) and aluminum bromide (AlBr3)] to give a resonance stabilized... 

B.ii. Isomerization. There are several problems associated with Friedel-Crafts alkylation. The first occurs when primary and secondary halides are used, because the cations formed from these substrates are subject to rearrangement. Reaction of benzene with 1-bromopropane and aluminum bromide (AlBr3), for... 

Aluminum bromide is dissolved in liquid HgS with exclusion of moisture. When solution is complete, the excess HgS is evaporated. Alternatively, dry KgS gas may be introduced into a solution of AlBr3 in CSg and the precipitated crystals filtered with exclusion of moisture. 

In the study of the l-methyl-3-ethylimidazolium bromide - aluminum bromide systems, the VFT parameters for the different compositions were fitted as a function of X (AlBr3 mole fraction) to cubic polynomial equations of the form...
