METHOD FOR PRODUCING HALOGEN COMPOUND, METHOD FOR PRODUCING POTASSIUM SALT, AND POTASSIUM SALT
Document Type and Number:
WIPO Patent Application WO/2015/159672
Kind Code:
A1
Abstract:
Provided is a method which is capable of efficiently producing a halogen compound that is useful as a precursor for a compound which is favorably used particularly in optical materials in general. A method for producing a halogen compound, which is characterized by comprising a step for producing a halogen compound represented by general formula (2) by reacting a compound represented by general formula (1) with a halogenation agent.
(In general formula (1), R1 represents a linear or branched alkylene group; R2 represents an aromatic ring-containing group that has a carbon atom constituting the aromatic ring in the binding site with the oxygen atom expressed in the formula; and n represents 1 or 2, and in cases where n is 2, the two R1 moieties may be the same as or different from each other.)
(In general formula (2), R1, R2 and n are as defined in general formula (1); and X represents a halogen atom, and in cases where n is 2, the two X moieties may be the same as or different from each other.)
