An Extremely Powerful Acylation Reaction of Alcohols with Acid Anhydrides Catalyzed by Trimethylsilyl Trifluoromethanesulfonate
The Journal of Organic Chemistry, 1998Co-Authors: Panayiotis A. Procopiou, Simon P. D. Baugh, Stephen Flack, Graham G. A. InglisAbstract:Trimethylsilyl Trifluoromethanesulfonate is an excellent catalyst for the acylation of alcohols with acid anhydrides. Highly functionalized primary, secondary, tertiary, and allylic alcohols, and phenols, were acylated cleanly and efficiently and in a fraction of the time used under the standard DMAP conditions.

TMS·OTf-Catalyzed α-bromination of carbonyl compounds by N-bromosuccinimide
Tetrahedron Letters, 2006Co-Authors: Samar Kumar Guha, Bo Wu, Woonphil BaikAbstract:Abstract Various carbonyl compounds undergo α-bromination reaction under a mild and practical condition utilizing N -bromosuccinimide (NBS), catalyzed by Trimethylsilyl Trifluoromethanesulfonate (TMS·OTf). This method is also effective for the side-chain bromination of heteroaromatic carbonyl compounds without the ring brominations.
