Preparation of 1-iodo-2,2-dimethylpropane
Methyl iodide (1.4 moles), triphenyl phosphite (1 mole), and neopentyl alcohol (1 mole) are heated in a bath for 24 hours, whereby, owing to continuing consumption of methyl iodide, the internal temperature rises from 75° to 130°. The crude 1-iodo-2,2-dimethylpropane and the phenol are distilled off in a vacuum and the distillate is washed with ice-cold, dilute sodium hydroxide solution, and water until free from phenol. The product contains about 6% of terf-pentyl iodide, to remove which it is shaken for 5 hours with three times its volume of water which is then discarded. The organic layer is next shaken with its own volume of 0.1N-aqueous silver nitrate, washed with water, dried, and fractionated. This gives a 53-57 % yield of 1-iodo-2,2-dimethylpropane of b.p. 71°/100 mm.
