2,3-Dimethyl-2-butene Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Uses

2,3-Dimethyl-2-butene was used in the preparation of thexyl NHC-borane (diMe-Imd-BH2thexyl).

General Description

2,3-Dimethyl-2-butene undergoes hydrolysis to form hydroxyl radical.

Purification Methods

Purify it by GLC on a column of 20% squalene on chromosorb P at 50o [Flowers & Rabinovitch J Phys Chem 89 563 1985]. Also wash it with 1M NaOH solution followed by H2O. Dry it over Na2SO4, distil it over powdered KOH under nitrogen and pass it through activated alumina before use. [Woon et al. J Am Chem Soc 108 7990 1986, Wong et al. J Am Chem Soc 109 3428 1987, Beilstein 1 IV 853.]
