Synthetic example 1

[0254]

[0255]

[0256] Compound (I-1D) was synthesized by the method described in "Journal of Chemical Crystallography" (1997); 27(9); p.515-526.

[0257]

[0258] Compound (I-4A) was synthesized according to the synthesis method of compound (I-4A) described in JP-A-2016-081035.

[0259]

[0260] 15.5g (67.4mmol) of carboxylic acid compound (I-4A), 185mL of ethyl acetate, 46mL of N,N-dimethylacetamide and 60mg of 2,6-di-tert-butyl-4-methyl Phenol was mixed, and the internal temperature was cooled to 0°C. To the mixture was added dropwise 7.75 g (65.1 mmol) of thionyl chloride at an internal temperature of 0 to 5°C. After stirring at 5°C for 60 minutes, a solution of 6.85 g (27.6 mmol) of compound (I-1D) and 52 mL of THF (tetrahydrofuran) was added dropwise at an internal temperature of 0 to 8°C.

[0261] Thereafter, 16.8 g of N,N-diisopropylethylamine was added dropwise at an internal temperature of 0 to 10°C. After stirring for 1 hour at an internal temperature of...

Synthetic example 2

[0265]

[0266]

[0267] Compound (III-3Db) was synthesized by the method described in "Journal of Organic Chemistry" (2004); 69(6); p.2164-2177.

[0268]

[0269] 5.0 g (15.3 mmol) of compound (III-3Db), 1.66 g (16.80 mmol) of methyl cyanoacetate, and 25 mL of isopropanol were mixed, and stirred under reflux for 3 hours. After cooling to room temperature, 50 mL of water was added to the mixture, and the precipitated crystals were filtered. The obtained crystals were washed with a mixed solution of water-isopropanol (10:1) and a 0.5N hydrochloric acid solution, dissolved in N,N-dimethylacetamide, and filtered. Water was added to the obtained filtrate, and the precipitated crystals were filtered to obtain 2.2 g (7.82 mmol) of compound (III-3D) (yield 51%).

[0270]

[0271] Compound (I-1D) in the synthesis method of compound (I-4) described in Example 1 was changed to compound (III-3D), and the compound ( III-3) (yield 86%).

Abstract

The present invention provides a cured product which is obtained by curing a curable composition that contains a compound represented by general formula 1, and which has a birefringence delta n (587 nm) larger than or equal to 0.00 and smaller than or equal to 0.01 and is suitable for the production of an optical member. In general formula 1, Ar represents an aromatic ring group represented by general formula 2-2 or the like; in general formula 2-2, each of Z1 and Z2 represents a hydrogen atom, a methyl group or the like, each of A1 and A2 represents -S- or the like, and X represents C(Rz)2 (wherein Rz represents a substituent, and the two Rz moieties may form a ring) or the like, each of L1 and L2 represents a single bond, -O-, -OC(=O)-, -OC(=O)O-, -OC(=O)NH- or the like, each of Sp1 andSp2 represents a single bond or a divalent linking group, and each of Pol1 and Pol2 represents a hydrogen atom or a polymerizable group, provided that the compound represented by general formula 1 hasat least one polymerizable group. General formula 2-2.

Description

technical field [0001] The present invention relates to a cured product, an optical component, a lens, a compound and a curable composition. Background technique [0002] Conventionally, glass materials have been used for optical parts of camera modules such as cameras, video cameras, mobile phones with cameras, video phones, and walkie-talkies with cameras. Glass materials have various optical properties and are excellent in environmental resistance, so they are conveniently used, but they are not easy to reduce in weight or size, and have disadvantages such as poor processability and productivity. On the other hand, cured resins can be mass-produced and have excellent processability, so they have been used in various optical components in recent years. [0003] In recent years, along with miniaturization of imaging modules, downsizing of optical components used in the imaging modules has been demanded. However, downsizing of the optical components will cause a problem of ...
