Abstract

... TRITYLPOTASSIUM A NEW DEHYDROHALOGENATION REAGENT Douglas R. Anton and Robert H. Crabtree Department of Chemistry Yale University New Haven, Connecticut, USA ABSTRACT: Ph3CK rapidly dehydrohalogenates secondary alkyl bromides and iodides at 0 to give olefins in very high yield (> 90%) Dehydrohalogenation of alkyl halides is often slow. ... d) in the presence of cyclohexanone (1 equiv.) e) using Ph3CLi f) after r. g) after 1 hr. ...
