Abstract

1,1-Dibromo-2-arylethenes are usually prepared by Wittig-type olefination of aryl aldehydes with triphenylphosphine and carbon tetrabromide. [3] [10a] More recently, they have also been formed via tandem oxidation-Wittig reaction of activated benzyl alcohols [10b] or through the intermediacy of hydrazones. [10c] However, the necessity to use equimolar amounts of phosphoric reagents and/or carbon tetrabromide limits the appeal of these methodologies as a result ...
