 Title    Magnesiumorganische Innerkomplexe, Teil II [1] Ethyl(dialkylaminoalkyl)-und Ethyl(4-alkoxybutyl)magnesium-Verbindungen Organomagnesium Inner Complexes, Part II [1] Ethyl(dialkylam inoalkyl)-and Ethyl(4-alkoxybutyl)magnesium Compounds  
 Abstract    The reaction o f bis(dialkylam inoalkyl)-and bis(4-alkoxybutyl)m agnesium inner com plexes with M gEt2 leads to the form ation of ethyl(dialkylam inoalkyl)-and ethyl(4-alkoxybutyl)m agnesium com pounds. The X -ray crystal structures o f ethyl(3-N ,N -dim ethylam inopropyl)m agnesium and ethyl(3-N -cyclohexyl-3-N -m ethylam inopropyl)m agnesium confirm that the com pounds are dim eric with the a-C -atom o f the chelating ligand bridging the magnesium atoms. The difference in reactivity of the M g —Et and M g—C"H2nX bonds (X = NR 'R ", O R) makes itself apparent in the reaction of these com plexes with ethylene: up to six ethylene m olecules are inserted, whereby in the case of the ethyl(4-alkoxybutyl)m agnesium com pounds insertion occurs preferentially into the M g—Et bond w hereas in the case o f the ethyl(dialkylam inoalkyl)m agne-sium com pounds both bonds are equally reactive.
