A nuclear magnetic resonance rate study of N,N-dimethylformamide complexes with AlCl3, BeCl2, GaCl3, SbCl5and TiCl4

Abstract
A nuclear magnetic resonance rate study of complexes of N,N-dimethylformamide (DMF) with AlCl3, BeCl2, GaCl3, SbCl5 and TiCl4 has been carried out. Measurements were made possible by the observation of separate resonance signals for bulk and complexed DMF in all solutions. Rate constants at 290°k varied from 2 sec-1 for the AlCl3. (DMF) n system to about 150 for the BeCl2. (DMF) n solution. Activation energies for the exchange process were also measured for all solutions.
