Problems solved by technology

[0005] However, in the above-mentioned method, in order to selectively obtain the tri-ortho-position metallization complex, it is necessary to use 50 to 100 equivalents of a large excess of ligands relative to the iridium raw material. When expensive ligands are used in the raw materials, economically unfavorable
[0006] In the above Ir(acac) 3 In the method used as a raw material, there are problems such as that the low-boiling point component acetylacetone is generated, and the reaction temperature cannot be raised to a higher temperature due to the reflux of the low-boiling point component, and the ortho-position metallization complex cannot be efficiently synthesized.

Embodiment 1

[0041] use figure 1 The device shown, made of iridium(III) tris(2-phenylpyridine-N,O)[Ir(ppy) 3 ]Salt. Ir(ppy) 3 The synthetic reaction formula of is as follows.

[0042] Reaction 1

[0043]

[0044] 1.0 g (2.04 mmol) iridium-acetylacetone complex [Ir(acac) 3 ], 1.1g (7.10mmol) of 2-phenylpyridine and 5ml of glycerin were added into the flask to form a reaction solution, and the microwave of 2.45GHz wavelength was irradiated while nitrogen bubbling was carried out. Set the microwave output power to 300W and the temperature to 200°C. This preset temperature of 200°C is higher than the boiling point of acetylacetone of 140.4°C and lower than the boiling point (decomposition temperature) of glycerol of 290°C. The temperature of the reaction solution rises only to about 170° C. at first, and when acetylacetone, a low-boiling point component, begins to be distilled off after about 10 minutes, the temperature of the reaction solution rises.

Embodiment 2

[0053] As in Example 1, use figure 1 The manufacturing apparatus shown, the synthesis of iridium (III) three (2-phenylquinoline-N, O) [Ir (ppq) 3 ]. The reaction formula is shown below.

[0054] Reaction 2

[0055]

[0056] 1.0g (2.04mmol) of Ir(acac) 3 , 1.45g (7.10mmol) of 2-phenylquinoline and 5ml glycerin are added in the 100ml glass eggplant-shaped flask, the same as in Example 1, the irradiation output power is a microwave of 150W, and the set temperature is 200 ℃ to start the reaction. The temperature of the reaction solution initially rises only to about 170° C., rising when distilling off from acetylacetone starts. When the temperature of the reaction solution reached about 200°C, the target product was produced. After 15 minutes from the start of the reaction, the reaction was terminated, and the reaction solution was left to cool. 20ml of dichloromethane was added, only the dichloromethane layer was extracted, and purified by column chromatography (filler: ...

Abstract

A method of producing an organic compound, which includes the steps of irradiating a reaction solution with an electromagnetic wave having a wavelength range of 900 MHz to 30 GHz to heat the solution, thereby producing the organic compound, and removing a low-boiling point component produced through the reaction from a reaction system to facilitate the reaction.

Description

technical field [0001] The present invention relates to a method for producing an organic compound by irradiating a reaction solution with electromagnetic waves and heating it, and an apparatus for producing the same. Background technique [0002] Organic electroluminescent (EL) elements are expected to be new types of self-luminous elements. Recently, phosphorescent light-emitting materials have attracted attention as high-efficiency light-emitting materials in organic EL elements. Especially in recent years, it was found that by using iridium's ortho-metallation (ortho-metallation) coordination compound iridium (III) tris (2-phenylpyridine-N, O) as a light-emitting material, high-efficiency light emission was achieved. With this discovery as an opportunity, the development of ortho-metallized coordination compounds with iridium or platinum as the central metal has become increasingly active. [0003] Known, the synthetic method of the tri-ortho-position metallization coo...
