Abstract

Trifluoroacetylation is important for the protection or activation of functional groups in organic and bioorganic synthesis. 1 Conventional reagents for trifluoroacetylation all have drawbacks or limitations:(i) trifluoroacetic anhydride2 has a low boiling point (39.5 C), is moisture sensitive, and is also too reactive for some applications;(ii) S-ethyl trifluorothioacetate forms the bad smelling by product ethanethiol; 3 (iii) ethyl ...
