General Description

2-Iodo-2-methylpropane was degraded by reductive dehalogenation with nickel-aluminum alloy in potassium hydroxide solution.

Purification Methods

Vacuum distillation has been used to obtain a distillate which remained colourless for several weeks at -5o. More extensive treatment has been used by Boggs, Thompson and Crain [J Phys Chem 61 625 1957] who washed with aqueous NaHSO3 solution to remove free iodine, dried this for 1hour over Na2SO3 at 0o, and purified it by four or five successive partial freezings of the liquid to obtain colourless material and was stored at -78o with Ag wool.
