Molecular Dynamics of the Dimerization of NaB phi4 in 1,2-Dimethoxyethane andTetrahydrofuran

摘要

New experimental microwave dielectric relaxation, electrical conductance andultrasonic relaxation kinetic data are reported for solutions of sodium tetraphenylborate (NaB phi4) dissolved in 1,2-dimethoxyethane (1,2-DME) and tetrahydrofuran (THF). 1,2-DME is a bidentate ether solvent, whereas THF is monodentate. NaB phi4 is strongly associated to ion pairs, and these ion pairs are dimerized to a considerable extent in both ether solvents.
