Abstract

Reactive intermediates in the Friedel-Crafts acylation of aromatic donors are scrutinized upon their successful isolation and X-ray crystallography at very low temperatures. The X-ray-structure examinations of aliphatic and aromatic acylium electrophiles isolated as crystalline salts that indicate the origins of their electrophilic reactivity are analyzed.

6. Isolation and X-ray structures of labile benzoic- and acetic-acidium carbocations

Author

Abstract

New carbocationic salts are prepared by controlled hydration of the corresponding benzoylium salts and isolated in pure crystalline form. Precise X-ray structural analyses reveal the structure of the carboxylic-acidium functionality.
