WebMar 25, 2013 · Here we report the homogeneously-catalyzed etherification of glycerol with short chain alkyl alcohols. Among the large variety of Bronsted and Lewis acids tested, we show here that metal triflates are not only the most active but are also capable of catalyzing this reaction with an unprecedented selectivity. In particular, in the presence of Bi(OTf)3, … Webacid-sensitive substrates were well tolerated. As an alternative approach, Hendrickson’s reagent, obtained from triphenylphosphine oxide and triflic anhydride, was employed in …
