Yield	Reaction Conditions	Operation in experiment
83%	With pyridine; for 3.5h;Reflux;	1-(2-hydroxyphenyl)ethanone O-acetyl oxime (2) (2.89 g, 15 mmol) was heated under reflux with anhydrous pyridine (25 mL) for 3.5 h. Following reflux, the dark yellow reaction mixture was allowed to cool to room temperature and acidified with 5 N HCl (approximately 100 mL). The mixture was extracted with ether (3 × 75 mL). The ether layers were pooled, washed with 1 N HCl (75 mL), dried over anhydrous sodium sulfate, and evaporated under vacuum to give yellow-colored, oily residue as crude product. The crude product was purified using column chromatography with hexane/EtOAc (25:2) as the eluting solvent. Fractions containing the desired compound were combined and dried under vacuum to give 3 as colorless oil.

Yield	Reaction Conditions	Operation in experiment
79%	With potassium phosphate; fac-Ir(ppy)3; In dimethyl sulfoxide; at 20℃; for 48h;Inert atmosphere; Schlenk technique; Sealed tube; UV-irradiation;Catalytic behavior;	General procedure: The oven-dried Schlenk tube (10 mL) containing a stirring bar was charged with benzo[d]isoxazoles 1 (0.5 mmol, 1.0 equiv.), BrCF2CO2Et (202.98 mg, 1.0 mmol, 2.0 equiv.), K3PO4 (212.27 mg, 1.0 mmol, 2.0 equiv.) and fac-Ir(ppy)3 (6.55 mg, 0.01 mmol, 0.02 equiv.). Then the tube was sealed and evacuated and back-filled with nitrogen for 3 times. Last, anhydrous DMSO (1 mL) was added via syringe. The resulting mixture was irradiated by 8 W blue LEDs light (460-470nm) in room temperature for 48 h. Then, the mixture extracted by ethyl acetate (10 mL), washed with water (10 mL×3) and dried over Na2SO4, the solvents were evaporated under vacuo, and the obtained crude product was purified by silica gel column chromatography (petroleum ether/AcOEt = 20/1) to give the pure desired product 2.
