2-[(2-Hydroxy-2,2-diphenylethyl)(methyl)amino]- N , N -dimethylethanaminium bromide

The title compound, C19H27N2O+·Br−, is the hydrobromide of the trapping product of lithiated N,N,N′,N′-tetramethylethylenediamine (TMEDA) with benzophenone. Thereby, the N atom of the NMe2 group is selectively protonated and the respective trapping product represents a potential tridentate ligand wi...

Summary:The title compound, C19H27N2O+·Br−, is the hydrobromide of the trapping product of lithiated N,N,N′,N′-tetramethylethylenediamine (TMEDA) with benzophenone. Thereby, the N atom of the NMe2 group is selectively protonated and the respective trapping product represents a potential tridentate ligand with one O and two N donor atoms. The H atoms at N (H2N) and O (H1O) are involved in hydrogen bonds with the Br−. The molecular structure shows all donor atoms to be arranged on one side of the molecule, thus indicating a potential threefold coordination of a Lewis acid.
