Nuclear Magnetic Resonance Spectroscopy. Effect of N,N,N',N'-Tetramethylethylenediamine on the Schlenk Equilibrium of Ethylmagnesium Bromide

Abstract

The composition of Grignard reagents has been studied extensively by nuclear magnetic resonance spectroscopy and other physical techniques. Recently Parris and Ashby using nmr spectroscopy, observed both dialkyl- and alkylmagnesium species in Grignard solutions from methyl and tert-butyl halides. Earlier Evans and coworkers5 had observed diarylmagnesium and arylmagnesium halides by both fluorine and proton magnetic resonance. We wish to report the observation of diethylmagnesium and ethylmagnesium bromide in tetrahydrofuran solutions containing N,N,N',N'-tetramethylethylenediamine.
