Trifluoromethyl ketones (TFMKs) significantly contribute to biologically active compounds and special materials. TFMKs can be prepared by “trifluoroacetic ester/ketone metathesis” along with the accompanying products, aromatic acid esters. As an important extension of our previous studies on the use of aryl alkyl ketones, wherein the separation of the resulting TFMKs and aromatic acid esters proved...
A highly selective and atom efficient ‘trifluoroacetic ester/ketone metathesis’ has been sincerely witnessed. Enolizable alkyl (at least two non-hydrogen atoms) aryl ketones were found to react readily with ethyl trifluoroacetate under the promotion of NaH to afford trifluoroacetic ester/ketone exchange products, trifluoromethyl ketones (TFMKs), and aromatic acid esters, which were quite different...
