Bromopentane -Amyl bromide

Dibromopropane 1-Bromobutane (w-Butyl bromide) 1-Bromopentane ( -Amyl bromide) 1-Bromohexane 1-Bromoheptane 1-Bromooctane 1-Bromodecane... 

Bromopentane. Proceed as for n-Amyl Bromide, but use 88 g. (108 ml.) of methyl n-propyl carbinol (2-pentanol), b.p. 118-5°. During the washing with concentrated hydrochloric acid, difficulty may be experienced in separating the acid layer this is overcome by adding a little water to decrease the density of the acid. Distil the purified product through a fractionating colunm some amylene passes over first, followed by the 2-bromopentane at 115-118° (120 g.).

Grignard reagent from -amyl bromide, 16, 41 from benzyl chloride, 10, 4 17, 89 from bromomesitylene, 11, 66 from a-bromonaphthalene, 11, 80 from 2-bromopentane, 11,84 from -butyl bromide, 15,11 from ethyl bromide, 11, 98 17, 48 from iso propyl bromide, IS, 48... 

The 2-bromopentane used in this preparation was prepared by the action of hydrobromic acid on secondary amyl alcohol (methyl M-propyl carbinol) obtained from Stanco Distributors, Inc. Other commercial straight chain amyl alcohols when converted to the bromides gave a pentane boiling at 33-3 50, showing that a considerable quantity of iso-pentane was present.
