WebApr 12, 2024 · Later, a triflic acid-catalyzed chemo- and site-selective C–H bond functionalization of free phenols 170 with 1,3-dienes 169 was realized by Liu et al. in 2024. A series of para-selective allyl phenols 171 were obtained with 40–88% yields under mild conditions in a site-selective manner. 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, …
