YieldReaction ConditionsOperation in experiment
90.4% In 1,2-dimethoxyethane; at 198 - 200℃; for 1.1h;Microwave irradiation; Inert atmosphere; 300 g of 2-phenylpyridinato, 30.1 g of a chlorine-bridged iridium dimer (D-1) and 3 L of special-grade ethylene glycol were placed in a 6 L separable flask, and the flask was set in a cavity-type microwave irradiation apparatus (SMW-124 manufactured by Shikoku Instrumentation CO., Inc.). An argon gas was blown into the reaction solution for 30 minutes, the reaction solution was thereafter irradiated with a microwave (2450 MHz) at 6 kW while the reaction solution was magnetically stirred, the temperature was elevated from room temperature to a boiling state (around 198° C. to 200° C.) in about 6 minutes, and the reaction solution was further irradiated with a microwave at 6 kW for an hour under an argon atmosphere, and reacted at around 198° C. to 200° C. The reaction solution was cooled to room temperature, and thereafter the reaction solution was filtered to obtain a yellow solid. The yellow solid was washed with methanol, pure water and methanol again, thereafter dried in a vacuum, and recrystallized from a mixed solvent of DMF and methanol to obtain a complex of tris-orthometallated iridium (T-1) described in chemical formula (chemical formula 11) (yield amount: 33.5 g; yield: 90.4percent). The product was analyzed by HPLC (Prominence manufactured by Shimadzu Corporation; detected wavelength: 300 nm), and resultantly found to be a mixture of a facial isomer and a meridional isomer at a ratio of 99.2:0.8 (molar ratio).
85.9% In a Schlenk's flask equipped with a reflux condenser was placed (1,5-cyclooctadiene)iridium(I) chloride dimer (500 mg, 0. 744 mmol, 1 equivalent) and the interior of the flask was substituted with nitrogen. There were successively added 2-ethoxyethanol (5 mL, s/s=10) and 2-phenylpyridine (468 muL, 3.274 mmol, 4.4 equivalents), and the mixture was stirred in a nitrogen atmosphere under refluxing (135°C) for 3 hours. The resulting yellow suspension was cooled to room temperature, to which was added silver (I) trifluoromethanesulfonate (573 mg, 2.232 mmol, 3.0 equivalents), and further stirred at room temperature for 10 minutes to give a dark brown suspension. There was added an additional amount of 2-ethoxyethanol (7 mL, s/s=14) and then dropwise added 2-phenylpyridine (638 muL, 4.464 mmol, 6.0 equivalents), and the mixture was further stirred under refluxing for 3 hours to give an ocher suspension. The solvent was distilled off from the reaction mixture under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: dichloromethane). The column fractions were condensed, and the resulting yellow solid was recrystallized from hexane/dichloromethane to give 837 mg of the title compound (V-i) as yellow powder in 85.9percent yield. 1H NMR (500MHz CD2Cl2) : delta 6.72-6.81 (m, 6H), 6.85-6.93 (m, 6H), 7.56 (ddd, J=0.8, 1.6, 5.5Hz, 3H), 7.62-7.69 (m, 6H), 7.89-7.94 (m, 3H).
83.4% With silver trifluoromethanesulfonate; In 2-ethoxy-ethanol; at 135℃; for 3h;Heating / reflux; In a Schlenk's flask were placed Compound (II-i) (Bis(2-phenylpyridinato-N,C2')iridium(III) chloride dimer) produced in Example 1 (200 mg, 0.187 mmol, 1 equivalent) and silver(I) trifluoromethanesulfonate (144 mg, 0. 561 mmol, 3.0 equivalents), and the interior of the flask was substituted with nitrogen. There were added 2-ethoxyethanol (1 ml, s/s=5) and 2-phenylpyridine (163 muL, 1.122 mmol, 6.0 equivalents), and the mixture was stirred under refluxing (135°C) for 3 hours. The resulting ocher suspension was condensed, and the residue was purified by silica gel column chromatography (eluent: dichloromethane). The column fractions were condensed, and recrystallized from hexane/dichloromethane to give 208 mg of the title compound (V-i) as yellow powder in 83.4percent yield. NMR data of the product was identical to that of Example 11.
78% Step Two:Added 1200 ml of Ethylene Glycol ether to 3 L of four-neck flask, followed with 18 g of Chlorendic compounds, stirred, Nitrogen gas filled in, then heated and refluxed. When the reflux occurred in the flask, added 12 g of solid sodium carbonate all at once. Dissolved 2-Phenyl Pyridine in 100 ml of Glycerol, and then dripped the mixture in forty minutes by using constant pressure drop funnel. Refluxed with stirring, with sampling interval 1 hour, and 2-3 hours later terminated the reaction. (HPLC: products 95percent-97percent)Cooled the reaction system, added 5.5 L of ethyl acetate, and then rinsed with 4 L.x.3 DI water. Dried the organic phase and concentrated solvent with 200 g of Magnesium Sulfate, and deep yellow solid substances reached. By using Methyl Cyanide, the deep yellow solid substances were recrystallized and 15 g of luminous yellow solid substances with 78percent of yield rate reached.1H-NMR (CDCl3, 400Hz): 7.84 (m, 3H), 7.58 (m, 6H), 7.48 (m, 3H), 6.83 (m, 6H), 6.69 (m, 6H).

YieldReaction ConditionsOperation in experiment
94% In water; at 205℃; for 48h;Inert atmosphere; Sealed tube; Iridium (III) chloride anhydrous (0.65 g, 2.18 mmol, 1 equiv), 2-phenylpyridine (3.74 mL, 26.1 mmol, 12.0 equiv), and 0.65 L of DI water (0.003 M with respect to IrCl3) is added to a 1 L Parr reactor. The reaction mixture is pressurized with argon (10.0 psi), stirred and then depressurized three times, and finally charged again with argon before sealing. The reaction mixture is heated to 205 °C for 48 h. Then the reactor is cooled to 20 with internal cooling coils. At the end of the experiment the reactor was left in the stand and the contents cooled to 20 °C using cold water. After cooling, the reactor is opened revealing an insoluble yellow solid on the surfaces and dispersed in the aqueous phase. All contents are transferred slowly to a 6 L separatory funnel aided by a large 5 cm glass funnel. Then the interior of the reactor is mechanically scraped (to extract the yellow material), with metal tongs, cotton balls (25 in total), and 500 mL of dichloromethane (DCM) from a spray bottle, and again all contents are added to the separatory funnel. While still in the funnel, the cotton is rinsed with 25 mL of DCM from a spray bottle and evenly pressed with tongs to release the yellow material from the cotton. After removing the cotton, the solution is then diluted with 2.5 L of DCM. The separatory funnel is shaken vigorously, allowed to settle and again shaken, and the organic layer is then slowly separated from the aqueous layer and the aqueous layer is further extracted with more DCM (3 × 10 mL), and the organic layers are combined. The aqueous layers are kept for future ligand recovery. The combined organic layer is washed with a 1 M HCl solution, with vigorous mixing prior to separation (3 × 900 mL). Each HCl wash is then back extracted with DCM (3 × 10 mL) to insure complete recovery of the product. After the final wash, the organic layer is filtered slowly (20 min) through a Celite (35 g) pad on top of a 150 mL medium porosity sintered glass funnel, into a 3 L round-bottomed flask, and then dried with 30 g of MgSO4. After filtering the drying reagent using a 4 L Erlenmyer flask fitted with a 5 cm funnel/cotton plug, a homogenous aliquot is removed for NMR analysis. Finally, the solvent is removed in batches by transferring to a 2.5 L round-bottomed flask by rotary evaporation (35,30 mm Hg, 150 rpm) to afford 1.35 g (94percent) of Ir(ppy)3 as a bright yellow solid.
