Metal triflate Lewis acids can also be dispersed in ionic liquids for catalytic applications. Acetylation of alcohols with acetic anhydride and acetic acid has been reported with Cu(OTf)2, Yb(OTf)3, Sc(OTf)3, In(OTf)3, HfClq. (THF)2, and InCl3 in ionic liquids that consist of [BMIM] and the anions BF4, PF, or SbF 166). With lmol% acid, all the catalysts in [BMIMJPF showed >99% acetylation products in acetyl anhydride acetylation of benzyl alcohol. Sc(OTf)3 showed the best yield with recycling, with a 25% drop in yield after two cycles. A relatively long reaction period was needed to obtain a high yield (95-98%) for the acetylation of benzyl alcohol with acetic acid, indicating that the activities of the catalysts were... [Pg.193]

The mechanisms of modification are different and depend on the chemical molecules used for the reactions. The anhydride of succinic acid reacts with lysine residues, a-amino groups of proteins and free thiol groups. During succinylation, proteins lose their globular structure and undergo aggregation by disulfide cross-binding with other whey proteins. Acetyl anhydride can modify tyrosine residues. [Pg.210]

ACETYL ANHYDRIDE (108-24-7) Forms explosive mixture with air (flash point 126°F/52°C). Reacts with water, forming acetic acid and liberating a large amount of heat. Reacts with alcohol, forming ethyl acetate. Reacts violently with alkaline materials (e.g., potassium hydroxide or sodium hydroxide), barium peroxide, boric acid, chromic trioxide,... [Pg.19]

Acylation of hydroxyl groups by treatment with an acyl anhydride, such as acetyl anhydride, can be a useful derivatization step. Dry conditions are essential for derivatization of the sample with the acyl anhydride in dichloromethane or pyridine at 60-80°C for ca. 60 min. Acyl derivatives are stable and after evaporation of the reagents they can, if necessary, be purified before GC-MS analysis. [Pg.32]

A slightly different type of fluorous lanthanide complex, Yb[C(S02C6Fi3)2 (S02C8Fi7)]3, showed a modest catalytic activity in BTF, but was found to be an effective catalyst in perfluoromethyldecalin for the Friedel-Crafts acylation of arenes with an acid anhydride. For example, anisole reacted with acetyl anhydride in the presence of 10mol% of the catalyst in perfluoromethyldecalin at 110°C for 2h to give the product in an 82% yield. Furthermore, the catalyst was recovered in a 96% yield via extraction of the reaction mixture with hot perfluoromethyldecalin ( 85°C). A 77% conversion was obtained in a second reaction with the recycled catalyst. [Pg.91]
