The Uses of 3-Bromopentane
3-Bromopentane is a glass forming liquid used in the preparation of 2-(1-ethyl-propoxy)-isoindole-1,3-dione. Further, it is employed in organic synthesis.
Preparation
Isomerically pure 3-bromopentane could be prepared from tri-1-ethylpropyl phosphite and hydrogen bromide and solvolysed in 60% aqueous ethanol. The detection of about 1% rearrangement products in both acid and weakly alkaline conditions supports the view that carbonium ion intermediates are formed in the reaction of at least a proportion of the molecules[1].
General Description
3-Bromopentane is a glass forming liquid. The dielectric relaxation of 3-bromopentane was studied.
