Yield	Reaction Conditions	Operation in experiment
40%	With tert.-butylnitrite; boron trifluoride; In chlorobenzene; at 50 - 100℃; for 1.5h;	Example 11 Preparation of 3-fluoroquinoline 1 g (6.94 mmol) of <strong>[580-17-6]3-aminoquinoline</strong> in 10 ml of chlorobenzene is introduced dropwise over 10 minutes onto a heel of 0.66 ml (10.4 mmol, 1.5 mol. eq.) of BF3.2H2O at ambient temperature in a 50 ml three-necked flask equipped with a reflux condenser, a thermocouple and a stirring system. The reaction medium is then heated to 50 C. and then 1.2 ml (9.01 mmol, 1.3 mol. eq.) of t-butyl nitrite (purity 90%) are added at this temperature over 30 minutes. The reaction medium is brought to 100 C. and stirred for 1 hour. The yield of isolated product is 40%.
	With tetrafluoroboric acid; sodium bicarbonate; sodium nitrite; In diethyl ether; ethanol; water; ethyl acetate; toluene; Petroleum ether;	3-Fluoroquinoline 23.5 g of <strong>[580-17-6]3-aminoquinoline</strong> and 12.1 g of sodium nitrite in 20 cm3 of distilled water were added cautiously to 100 cm3 of tetrafluoroboric acid cooled to about 0 C., with vigorous stirring, and the reaction mixture was thus stirred for 30 minutes. The suspension was filtered, spin-filtered, washed with 3 times 30 cm3 of ice-cold tetrafluoroboric acid, 50 cm3 of ice-cold ethanol and 4 times 30 cm3 of diethyl ether. The solid was dried in a desiccator (2 kPa) in the region of 20 C. and then taken up in 200 cm3 of toluene and heated at a temperature in the region of 90 C. for 1 hour with stirring. After cooling to about 20 C., the phases of the reaction mass were separated by settling and the insoluble oil was washed with 3 times 100 cm3 of toluene and taken up in 110 cm3 of water, which was basified by slow addition of sodium hydrogen carbonate so that the pH was at about 8. The aqueous phase was extracted with 5 times 100 cm3 of diethyl ether and the organic phases were combined, washed with twice 50 cm3 of water, dried over magnesium sulfate and taken up with vegetable charcoal (3S), filtered and concentrated to dryness under reduced pressure (2 kPa) at a temperature in the region of 45 C. The oil was taken up in 50 cm3 of a 40-60 C. petroleum ether/ethyl acetate mixture (90/10 by volume) and the insoluble material was filtered off, rinsed with twice 25 cm3 of a 40-60 C. petroleum ether/ethyl acetate mixture (90/10 by volume) and dried in a desiccator under reduced pressure (2 kPa) at a temperature in the region of 20 C. The filtrate was concentrated to dryness under reduced pressure (2 kPa) at a temperature in the region of 40 C. The residue obtained was purified by chromatography under atmospheric pressure, on a column of silica gel (particle size 20-45 mu; diameter 5 cm; height 45 cm), eluding with a 40-60 C. petroleum ether/ethyl acetate mixture (90/10 by volume) and collecting 100-cm3 fractions. Fractions 20 to 31 were combined and then concentrated to dryness under reduced pressure (2 kPa) at a temperature in the region of 40 C. 13 g of 3-fluoroquinoline were obtained in the form of a colorless liquid. Mass spectrum: EI m/z=147 M+. base peak m/z=127 [M-HF]+. m/z=120 [M-HCN]+
	With tert.-butylnitrite; boron trifluoride diethyl etherate; In 1,2-dichloro-benzene; at 100℃; for 1h;	Tert-butylnitrite (4.6 ml, 38.7 mmol) was added dropwise over 15 min to a solution of quinolin-3 -amine (4.61 g, 32.0 mmol) and borontrifluoride-etherate (6 ml, 47.3 mmol) in dichlorobenzene (100 ml). The solution was heated to 100C. After stirring for for 1 h, the solution was cooled to ambient temperature and the dichlorobenzene was decanted leaving 3-fluoroquinoline as a black residue. Method [8] retention time 3.28 min by HPLC (M+ 148).

1.6 g	With tetrafluoroboric acid; sodium nitrite; In water; at 0 - 20℃; for 1h;	Quinolin-3 -amine (4 g, 27.7 mmol) was added to HBF4 (26 mL, 48 % aqueous solution) portionwise at room temperature, and the mixture was stirred at room temperature until it became homogeneous. The mixture was then cooled to 0C, and a solution of NaN02 (2.4 g, 34.8 mmol) in H20 (8 mL) was added dropwise, when the reaction mixture became heterogeneous. The mixture was stirred at 0C for 1 hour, then the mixture was filtered, and the filtered cake was washed with cold EtOH, then Et20. The resulting solid was dried under vacuum, then suspended in toluene in a round bottom flask and was refluxed for 1.5 hours. The resulting mixture was cooled to room temperature, and then poured into cold water. The organic layer was dried over Na2S04, and then concentrated in vacuo to obtain the desired product (1.6 g). LC-MS: m/z 148.1 (M+H)+

Yield	Reaction Conditions	Operation in experiment
78%		General procedure: An oven-dried reaction vessel (4 or 9 ml screw-cap vial) equipped with a stirring bar was allowed to cool to room temperature under vacuum. Activated 4 A molecular sieves (crushed, 50 mg), [Rh-2 ] (and solid substrates, 1.0 equiv.), were added under air. The vial was then depressurized and pressurized with argon gas three times before the addition of dry THF (1 M) (and liquid substrates, distilled over CaH2, 1.0 equiv.). Following the addition of 4,4,5,5-tetramethyl-1,3,2-dioxaborolane (2.0-4.0 equiv. as indicated), the glass vial was placed in a 150 ml stainless-steel autoclave under an argon atmosphere. The autoclave was pressurized and depressurized with hydrogen gas three times before the indicated pressure was set. The reaction mixture was stirred at 25-40 C for 24 h. After the autoclave was carefully depressurized, trifluoroacetic anhydride (3.0 equiv.) and CH2Cl2 (0.5 ml) were added to the crude mixture and stirring was continued for 10 min at room temperature. Alternatively, di-tert-butyl dicarbonate (3.0 equiv.), triethyl amine (3.0 equiv.) and CH2Cl2 (0.5 ml) were added to the reaction mixture and stirring was continued for 2 h at room temperature. The crude was then filtered over fritted funnel and the remaining solid was washed with ethyl acetate (2x 5 ml). The combined solution was concentrated under reduced pressure and submitted to column chromatography (pentane/ethyl acetate or pentane/dichloromethane) to obtain the final product. The indicated diastereoselectivities were determined by GC analysis or from the 19F NMR spectrum immediately after the reaction. NMR yield was calculated using hexafluorobenzene (20 μl, 0.173 mmol) as internal standard.

Themixture was stirred at room temperature for 15 min andwarmed to 110 C and was allowed to react for 12 h andquenched with 10 cm3of water. The solution was extractedwith dichloromethane (3 × 30 cm3).The combined organicphase was dried over MgSO4and concentrated to drynessunder reduced pressure. The residue was purified by columnchromatography to give the coupling product.
