Embodiment 1
[0089] Embodiment 1: the preparation of compound TM1
[0090]
[0091]
[0092] Under argon protection, compound C1 (2.36g, 20mmol), compound D1 (9.24g, 44mmol), potassium carbonate (5.5g, 40mmol), bis(tri-tert-butylphosphine) palladium (20.4 g, 0.04mmol), toluene (200ml), stirred under reflux for 5 hours, cooled to room temperature, extracted with toluene, washed with water, dried over anhydrous sodium sulfate, and purified by column chromatography to obtain intermediate A1 (3.1g, 62%) .
[0093] Under the protection of nitrogen, intermediate A1 (3.0g, 12mmol), iridium trichloride trihydrate (1.76g, 5mmol), and purified water (5ml) were successively added to the flask, and refluxed at 150°C for 12 hours to stop the reaction. 150 ml of distilled water was added to precipitate a precipitate, the reaction mixture was filtered, the filter cake was washed with absolute ethanol, and dried to obtain intermediate B1.
[0094] Add compound E1 (62.8mg, 0.4mmol) and n-hexane (10...
Embodiment 2
[0095] Embodiment 2: the preparation of compound TM11
[0096] Compound D1 in Example 1 was replaced by equimolar compound D2, and other steps were the same as in Example 1 to obtain compound TM11 (262 mg, 65%). Mass spectrum m / z: theoretical value: 1011.25; found value: 1013.52. Theoretical element content (%)C 55 h 46 IrN 8 : C, 65.33; H, 4.59; Ir, 19.01; N, 11.08; Measured element content (%): C, 65.31; H, 4.65; Ir, 19.00; N, 11.05. The above results confirmed that the obtained product was the target product.
[0097]
Embodiment 3
[0098] Embodiment 3: the preparation of compound TM16
[0099] Compound D1 in Example 1 was replaced by equimolar compound D3, compound F1 was replaced by equimolar compound F2, and other steps were the same as in Example 1 to obtain compound TM16 (298 mg, 62%). Mass spectrum m / z: theoretical value: 1203.59; found value: 1205.73. Theoretical element content (%)C 69 h 70 IrN 8 : C, 68.86; H, 5.86; Ir, 15.97; N, 9.31; Measured element content (%): C, 68.83; H, 5.92; Ir, 15.95; N, 9.30. The above results confirmed that the obtained product was the target product.
