✦ Synopsis

THE reaction of phenacyl halides with triphenylphosphine is known to give the corresponding phenacyltriphenylphosphonium halides via nucleophilic displacement of halogen. 3 We have found that secondary and tertiary abromoketones, in contrast, react with triphenylphosphine in refluxing benzene-methanol to give the debrominated ketone, triphenylphosphine oxide and methyl bromide. 4 The results are summarized in Table 1.
