3-Bromopentane synthesis

11synthesis methods
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].
