Paragraph 0049, (2018/04/10)
PROBLEM TO BE SOLVED: To provide a method that makes it possible to efficiently produce a halogen compound useful as a precursor of a compound that can be used suitably for optical materials in general. SOLUTION: A method for producing potassium salt includes the step for producing potassium salt represented by formula (1) by the reaction between a compound represented by formula (3), a cyclic carbonate ester compound, and potassium carbonate. [R2 is an aromatic ring-containing group having C constituting an aromatic ring at a binding site to O; n is 1 or 2; R1 independently represents an alkylene group].

Efficient multigram two-step syntheses of 4-(2-chloroethoxy)phenol and 4-(3-chloropropoxy)phenol in >70% yields starting from 4-hydroxybenzaldehyde and reagents with general formula Cl(CH2)nX (X = Cl, n = 2; X = OTs, n = 3) are proposed. 4-(2-Chloroethoxy)phenol can also be conveniently prepared from 4-methoxyphenol and 1,2-dichloroethane. The compounds thus obtained can be used in carbohydrate chemistry to synthesize glycosides bearing "universal" 4-(ω-chloroalkoxy)phenyl aglycons.

Paragraph 0049, (2016/10/08)
PROBLEM TO BE SOLVED: To provide a method capable of manufacturing a halogen compound useful as a precursor of a compound capable of being preferably used especially for optical system materials generally with high efficiency. SOLUTION: There is provided a manufacturing method of a halogen compound including a process of reacting a compound represented by the following formula (1) and a halogenation agent to produce a halogen compound represented by the following formula (2). In the formula (1), R1 is a linear or branched alkylene group, R2 is an aromatic ring-containing group having a carbon atom constituting an aromatic ring at a binding part with an oxygen atom represented in the formula, n is 1 or 2 and two of R1s may same or different when n is 2. In the formula (2), X is a halogen atom. COPYRIGHT: (C)2016,JPOandINPIT
