A-Bromo-»-caproic acid

It is best to distil the first low-boiling fractions with a water pump, since a considerable amount of hydrogen bromide is evolved. In order to obtain a light-colored product, the distillation should take place under as low pressure as possible. The a-bromo- -caproic acid boils at ii6-i25°/8 mm. The product obtained is sufficiently pure for most purposes upon redistillation, however, it comes over almost entirely between 128-13i°/io mm. [Pg.10]

This is a general method for preparing a-bromo acids. By using exactly analogous directions a-bromo- -caproic acid may be obtained in 65-70 per cent yields from w-butylmalonic ester a-bromo-isocaproic acid in 65-70 per cent yields from isobutylmalonic ester and a-bromo- 3-methyl valeric acid in 75-80 per cent yields from sec.-butylmalonic ester.
