Abstract
In konzentrierten ätherischen Lösungen liegen Grignard-Verbindungen überwiegend in der Form R_2Mg + MgX_2 vor. Die ^(13)C-chemischen Verschiebungen aliphatischer Grignard-Verbindungen sind linear korrelierbar mit denen entsprechender Kohlenwasserstoffe. Allyl-und Cyclopentadienylmagnesiumbromid zeigen austauschentartete ^(13)C-Spektren. Für alkyl-substituierte Benzole konnten die Linien zugeordnet werden. ^(13)C-NMR-Spectroscopic Investigations of Grignard Compounds Grignard reagents occur predominantly as R_2Mg + MgX_2 in concentrated diethyl ether solutions. The ^(13)C chemical shifts of Grignard reagents give a linear correlation with the chemical shifts of corresponding hydrocarbons. Exchange processes produce degenerate ^(13)C spectra for allyl- and cyclopentadienylmagnesium bromide. The resonance lines for alkyl-substituted benzenes have been assigned to specific carbons.
