Abstract
The Friedel-Crafts acylation of a hydrocarbon by an acylating agent containing bromoalkyl substituents gave a series of new ketones. Their subsequent dehydrobromination with potassium tert-butoxide gave high yields of aromatic ketones containing terminal vinyl groups. The reaction was conducted both with /beta/-bromoethylbenzene and with 4-(/beta/-bromoethyl)-benzoyl chloride and also with both compounds simultaneously. The structures of the synthesized compounds were confirmed by the PMR, IR, UV, and mass spectra and also by the data from elemental analysis.
