Bromoethane, hydrolysis

For example, the alkaline hydrolysis of bromoethane can be followed using conductivity measurements. As this reaction proceeds, the small and fast moving hydroxide ions are consumed and replaced by slower moving bromide ions. Therefore, the electrical conductivity decreases as the reaction proceeds. 

Bromoethane, C2H5Br, undergoes rapid hydrolysis in the presence of aqueous alkali. The products of the reaction are ethanol, C2H5OH, and bromide ions ... 

Two novel routes to triethylborane have been reported. Irradiation of bromoethane and aluminium powder with ultrasound gives ethyl aluminium sesquibromide which on treatment with triethoxyborane gives triethylborane in good yields and a laser initiated gas phase reaction between diborane and ethene gives yields of upto 91%. Allylic boranes have been prepared from allylpotassiiim derivatives and chloroboranes. Hydrolysis leads to the Isomerised olefin and the technique has been used to transform (+)-a-pinene into (+)-3-pinene. Condensation reactions between allylboranes and acetylenes have been developed into a convenient method for the synthesis of bicyclo[3.3.l]nonane derivatives. Mainly linear alkyl derivatives of 9-BBN have been synthesised from the, reaction of iron carbonyls and the organoborane in a Fischer-Tropsch type reaction. ...
