Yield	Reaction Conditions	Operation in experiment
96%	With K-10 clay In neat (no solvent) at 85℃; for 0.0833333 h; Microwave irradiation	General procedure: (2E)-1-(2-aminophenyl)-3-(2-fluorophenyl)prop-2-en-1-one (1), (2E)-1-(2-aminophenyl)-3-(3-fluorophenyl)prop-2-en-1-one (2), and (2E)-1-(2-aminophenyl)-3-(4-fluorophenyl)prop-2-en-1-one (3) (0.02 mol each) were dissolved in chloroform and uniformly adsorbed on the surface of K-10 clay (15 g each) in a Pyrex round bottomed flask. The solvent was evaporated under vacuum, and then the adsorbed material was transferred to a Pyrextube (2 cm diameter, 30 mL) and inserted inside the Milestone microwave oven. The mixture was heated using axed power of 350 W for 5 min at 85° C. The reaction mixture was dissolved in AcOEt (2 15 mL) and filtered off. The extract was evaporated to leave a crude mixture, which was purified by column chromatography over silica (hexane{AcOEt, 5:1) to afford the pure corresponding products (4, 5, and 6) in 92percent, 90percent, and 96percent yields,respectively; the assigned structures for the known compounds 2-(2-fluorophenyl)-2,3-dihydroquinolin-4(1H)-one(4), 2-(3-fluorophenyl)-2,3-dihydroquinolin-4(1H)-one (5), and 2-(4-fluorophenyl)-2,3-dihydroquinolin-4(1H)-one (6) were confirmed by their spectral properties (1 H, 13C/APT, 2D-COSY NMR, IR, and LC-MS/MS )and by comparison with literature data.

Yield	Reaction Conditions	Operation in experiment
90%	With iodine; In dimethyl sulfoxide; at 80℃; for 12.0h;	General procedure: A mixture of 2 (1 mmol) and iodine (1.5 mmol) inDMSO was warmed at 80C in an oil bath for 12 hours. On completion of the reaction, the reaction mixture was poured onto saturated solution of sodium thiosulfate. The precipitated solid was collected and the desired product was purified by column chromatography using silica gel (60x120 mesh) with increasing percentage of ethyl acetate in hexaneas eluting solvent. The physical data of compounds are provided below.

Yield	Reaction Conditions	Operation in experiment
30%		General procedure: To a solution of 2-(2-fluorophenyl)-2,3-dihydroquinolin-4(1H)-one (4), 2-(3-fluorophenyl)-2,3-dihydroquinolin-4(1H)-one (5), and <strong>[155370-03-9]2-(4-fluorophenyl)-2,3-dihydroquinolin-4(1H)-one</strong> (6) (2.41 g, 0.01 mol for each) in DMF (10mL each) was added KOH (1.12 g, 0.02 mol each) and the resulting mixture was stirred at room temperature for 1 h. Then alkyl bromide (0.03 mol each) was added dropwise, and the reaction mixture was stirred overnight at room temperature. Then the reaction mixture was poured into 20 mL of water. The resulting mixture was extracted with CH2Cl2 (2 x 20 mL). The combined organic layer was washed with brine, dried over Na2SO4 , filtered, and concentrated in a vacuum to give crude products 7a-k, 8a-k, and 9a-k, which were purified by column chromatography using a mixture of n-hexane-chloroform (8.5:0.5) as eluent (yields are in Tables 1, 4, and 7).
