Abstract

original image

The disproportionation of dimethylmagnesium to give novel organomagnesium ions is possible with the tripod ligand N,N′,N″-trimethyl-l,4,7-triazacyclononane (tacn). The cation in 1 has a triple-decker structure (shown on the right); the anion is the first trimagnesate, whose structure is intermediate to those of monomeric and polymeric compounds.
