Direct nuclear magnetic resonance observation of Me2Mg and MeMgBr in a diethyl ether solution of methylmagnesium bromide
Abstract
100 MHz n.m.r. spectra of dimethylmagnesium, methylmagnesium bromide, and a mixture of dimethylmagnesium and methylmagnesium bromide from +30 to –105° reveal the presence of MeMgBr and Me2Mg species in diethyl ether solution of the Grignard reagent.
