Keywords: | Acylation;Aliphatic compounds - Synthesis;Ketones - Synthesis;Anthraquinones - Spectra | Issue Date: | 2001 | Abstract: | Both pyrophosphoryl chloride and phosphorus oxychloride react with aryl-aliphatic acids to form mixed anhydrides which undergo intramolecular acylation to afford cyclic ketones without the addition of a Friedel-Crafts catalyst. Aryl and aroyl-benzoic acids could be cyclized to the corresponding anthrones and anthraquinones respectively. | URI: | http://hdl.handle.net/20.500.11889/3995 |
