Abstract

Abstract: The nmr spectra of 2-methylbutylmagnesium bromide and bis (2-methylbuty1) magnesium have been determined as a function of temperature in several ethers. At-30" the CHzMg hydrogens are magnetically nonequivalent and give rise to the AB portion of an ABX spectrum. With increasing temperature this pattern progressively collapses to Az of A2X. Analysis of the results reveals that changes among the nmr spectra are due to different ...
