-
Paragraph 0320-0322; 0330-0332, (2020/06/18)
PROBLEM TO BE SOLVED: To provide: a production method of a benzothiazole derivative; as well as a production method of a polymerizable compound produced from the benzothiazole derivative; a polymerizable composition including the polymerizable compound; a polymer obtained by polymerizing the polymerizable composition; and an optical isomer utilizing the polymer. SOLUTION: A production method of a compound represented by the following general formula (III) is provided, and also a production method of a polymerizable compound produced from the compound represented by the general formula (III), a polymerizable composition, a polymer obtained by polymerizing the polymerizable composition, and an optical isomer utilizing the polymer are provided. When the polymerizable composition containing the compound is polymerized and the obtained film-like polymer is irradiated with ultraviolet light, change of color and change of phase difference scarcely take place.

Paragraph 0172-0173, (2020/04/09)
PROBLEM TO BE SOLVED: To provide a manufacturing intermediate hardly generating discoloration and change of haze, when ultraviolet is radiated to a film-shaped polymer obtained by manufacturing a polymerizable compound and polymerizing a polymerizable composition containing the compound, and a manufacturing method of the manufacturing intermediate. SOLUTION: There are provided a compound represented by the formula (II), a manufacturing method of the compound, a polymerizable compound manufactured from the compound, a polymerizable composition, a polymer obtained by polymerizing the polymerizable composition, and an optical isomer using the polymer. In the formula, R1, R2 and L1 represent organic groups, n1 represents an integer of 1 to 4, when a plurality of L1 exist, it may be same or different, and neighboring L1 each other may form a condensed ring.

, p. 1025 - 1032 (2007/10/03)
The reaction of 2-(arylamino)-2-oxoacetates with PCl5 afforded 2-(arylamino)-2,2-dichloroacetates. The reaction of these compounds with aniline derivatives allowed a convenient synthesis of a great variety of 2-(arylamino)-2-(arylimino)acetamides. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
