Ws. Huang et al., A NEW AND SIMPLE APPROACH TO N-SUBSTITUTED TRIFLUOROACETIMIDOYL ARYL KETONES, Journal of fluorine chemistry, 74(2), 1995, pp. 247-250
Using 1,3-dimethylimidazolium iodide as a catalyst, the reaction of tr
ifluoroacetimidoyl chloride with an aromatic aldehyde in the presence
of sodium hydride gives N-substituted trifluoroacetimidoyl aryl ketone
