Title:

METHOD FOR PRODUCING AROMATIC COMPOUND HAVING ETHYNYL GROUP

Document Type and Number:

WIPO Patent Application WO/2023/048034

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a method for producing an aromatic compound having an ethynyl group by means of a simple and inexpensive coupling reaction using a halogen-containing aromatic compound.　The present invention is a method for subjecting an aromatic halogen compound and an ethynyl compound to a coupling reaction to produce an aromatic compound having an ethynyl group, wherein: the aromatic halogen compound is represented by general formula (1); the ethynyl compound is represented by general formula (2); the aromatic compound having an ethynyl group is represented by general formula (3); and the coupling reaction is carried out in an organic solvent having a nitrogen atom in the chemical structure thereof, in the presence of an amine, palladium carbon, a phosphorus compound, a copper compound, and an alkali metal salt. In the formulae, R is a polar group, B is a hydrogen atom or an alkyl group, X is a halogen atom, A is a hydrocarbon group having a hydroxyl group, or a trialkylsilyl group, and n is an integer of 1 to 3.
