Abstract

A neutral dimeric molecule in crystal form, the diisopropylamido turbo-Grignard reagent '(iPr2N)MgCl⋅LiCl' (see structure; blue N, red O, green Mg, yellow Cl, black C) separates into several charged ate species in dynamic exchange with each other in THF solution as determined by a combination of EXSY and DOSY NMR studies.
