| | GAMMA-CHLOROBUTYROPHENONE Usage And Synthesis |
| Uses | 4-Chlorobutyrophenone may be used in the preparation of silyl enol ether, Z-4-chloro-1-phenyl-1-trimethylsilyloxybut-1-ene. It may be used as starting material in the preparation of 8-arylimidazopyridines. | | Synthesis Reference(s) | Journal of the American Chemical Society, 79, p. 1455, 1957 DOI: 10.1021/ja01563a049 | | General Description | 4-Chlorobutyrophenone is a chloro ketone. Preparation of 4-chlorobutyrophenone is reported. | | Purification Methods | Fractionate the ketone several times using a short column. It recrystallises from pet ether at -20o as glistening white rosettes and is filtered at 0o, and dried in a vacuum desiccator over H2SO4. The semicarbazone has m 136-137o. [Conant et al.
