Conversion of alcohols to bromides using a fluorous phosphine
Desmaris, Laurence,Percina, Nathalie,Cottier, Louis,Sinou, Denis
, p. 7589 - 7591 (2003)
Reaction of alcohols with the fluorous phosphine-carbon tetrabromide complex in toluene or in a two-phase toluene-FC-72 system afforded the corresponding bromides in good yields. The fluorous-phosphine oxide is readily separated by liquid-liquid extraction, providing an alternative to the homogeneous triphenylphosphine-carbon tetrachloride conversion, as well as to the polymer-supported phosphine method. The fluorous phosphine oxide could be reduced and the product reused.
A novel protocol for the regioselective bromination of primary alcohols in unprotected carbohydrates or glycosides
Xue, Weihua,Zhang, Lifen
experimental part, p. 1429 - 1432 (2012/09/07)
The regioselective and efficient bromination of primary hydroxyl groups in unprotected carbohydrates or glycosides is successfully achieved by using (chloro-phenylthio-methylene)dimethylammoniumchloride (CPMA) in the presence of tetrabutylammonium bromide
