Abstract: It has been shown that both &, trans-and truns, trans-2, 3-dimethyl-l- phenylcyclopropanols and their corresponding acetates react stereospecifically with a variety of brominating agents to form bromo ketones with complete insersion of configuration at the site to which the bromine becomes attached. Thus the &, trans isomer gives only erythro-a-methyl-P-bromobutyrophenone and the trans, truns isomer gives exclusively the ...
