transformed to 4-quinolone or 4H-thiochromen-4-one products through intramolecular SNAr reaction, respectively. 4-Quinolone and 4H-thiochromen-4-one derivatives are readily synthesized in a tandem one-pot manner in good to excellent yields. Starting from (Z)-β-chlorovinyl ketones, an intermolecular nucleophilic addition of amines or sodium hydrogen sulfide to (Z)-β-chlorovinyl ketones was followed by elimination
