Complexes of bromine with hexamethylphosphoric triamide (HMPA) and with its polymeric analogue poly-HMPA
Abstract
The equilibrium constant of complexation of bromine with hexamethylphosphoric triamide (HMPA) has been determined by 1H n.m.r. spectroscopy by using a ‘competitive complexation’ method. Solid adducts of bromine with poly-HMPA, a polymer analogue of HMPA, have been isolated from chloroform solutions.
