2-Chloro-1,3-dimethylimidazolinium Chloride. 3. Utility for Chlorination, Oxidation, Reduction, and Rearrangement Reactions
摘要:
2-Chloro-1,3-dimethylimidazolinium chloride (1), which can act as a powerful dehydrating equivalent to DCC (2), is also applicable to chlorination, oxidation, reduction, and rearrangement under nearly neutral conditions. The utility of 1 for these reactions is described.
formation and experimental characterization of the first hexabromide dianion is presented. This dianion fills the last remaining gap in the series of polybromides from the tribromide [Br3]− to the undecabromide [Br11]−. The experimental results are compared to quantum‐chemical calculations. These calculations predict—based on electrostatic interactions—a T‐structure for the hexabromide dianion, while
