HMPA is a specialty solvent for polymers, gases, and organometallic compounds. It improves the selectivity of lithiation reactions by breaking up the oligomers of lithium bases such as butyllithium. Because HMPA selectively solvates cations, it accelerates otherwise slow SN2 reactions by generating more bare anions. The basic nitrogen centers in HMPA coordinate strongly to Li . HMPA is a ligand in the useful reagents based on molybdenum peroxide complexes, for example… WebAdditives Value beyond chemistry Photoinitiators for UV Curing Formulators’ Guide for Coatings.
