In this paper, a novel synthesis of tertiary amides from anionically activated aromatic trifluoromethyl groups is presented. Anionically activated trifluoromethyl groups react with secondary amines under aqueous conditions to afford tertiary amides. The mechanism involves initial elimination of hydrogen fluoride by an E1cB mechanism to afford an electrophilic quinone methide- or azafulvene-type intermediate

An intramolecular dehydrogenative (sp3)C–O bond formation in salicylamides can be initiated by an active Cu/O2 species to generate pharamaceutically relevant dihydro-oxazinones. Experimental findings suggest that stereoelectronic parameters in both coupling partners are controlling factors for site selectivity in bond formation. Mechanistic investigations including isotope labeling, kinetic studies
