Some co-ordination complexes of dimethyl- and diphenyl-magnesium with ethers and amines

Abstract

Co-ordination complexes of dimethyl- and diphenyl-magnesium with 1 mol. of tetramethylethylenediamine and 1,2-dimethoxyethane are described, the soluble complexes being monomeric in benzene solution. The bisamine complex of dimethylmagnesium can be sublimed without decomposition, but the others and the tetramethyl-o-phenylenediamine complex of dimethylmagnesium lose ether or amine when heated. Dimethylmagnesium and trimethylethylenediamine form a dimeric complex analogous to those derived from dimethyl-beryllium and -zinc.
