Abstract An alternative strategy for the mechanochemical defluorinative acylation of ortho-hydroxyarylenaminones has been developed to synthesise 3-acylchromones utilizing CF3-compounds via activation of the C−F bound of the trifluoromethyl group in the presence of ytterbia (Yb2O3). The current protocol tolerated a wide range of coupling substrates to access a library of diversely substituted 3-acylchromones under the mechanochemically induced domino cyclisation mode.
