So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Liu, Fei; De Oliveira Vigier, Karine; Pera-Titus, Marc; Pouilloux, Yannick; Clacens, Jean-Marc; Decampo, Floryan; Jerome, Francois researched the compound: Iron(III) trifluoromethanesulfonate( cas:63295-48-7 ).Electric Literature of C3F9FeO9S3.They published the article 《Catalytic etherification of glycerol with short chain alkyl alcohols in the presence of Lewis acids》 about this compound( cas:63295-48-7 ) in Green Chemistry. Keywords: glycerol alc etherification Lewis acid catalyst. We’ll tell you more about this compound (cas:63295-48-7).
Here we report the homogeneously-catalyzed etherification of glycerol with short chain alkyl alcs. 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, the targeted monoalkylglyceryl ethers were obtained with up to 70% yield. Although tested Bronsted acids were also capable of catalyzing the etherification of glycerol with alkyl alcs., they were found however less active and less selective than Bi(OTf)3. By means of counter experiments, we highlighted that the high activity and selectivity of Bi(OTf)3 may rely on a synergistic effect between Bi(OTf)3 and triflic acid, a Bronsted acid that can be released by in situ glycerolysis of Bi(OTf)3. The scope of this methodol. was also extended to other polyols and, in all cases, the monoalkylpolyol ethers were conveniently obtained with fair to good yields.
Different reactions of this compound(Iron(III) trifluoromethanesulfonate)Electric Literature of C3F9FeO9S3 require different conditions, so the reaction conditions are very important.
