The Uses of 1-Iodo-3-methylbutane
1-Iodo-3-methylbutane can be used for organic synthesis or used as solvents.
Preparation
Synthesis of 1-Iodo-3-methylbutane: Bromo-3-methylbutane (30.2 g, 0.20 mol) was added dropwise to a mixture of NaI (44.97g, 0.30 mol) and acetone (500 mL). The mixture was refluxed overnight. The mixture was filtrated and the filter cake was washed with (2 x 50 mL) acetone. The acetone was evaporated under reduced pressure. 1-Iodo-3-methylbutane was distilled under vacuum to give 13.8g (35 %) (b.p. 25 - 35°C, 15 mmHg).
