発明の名称 (英語) METHOD FOR PREPARING COUPLED BODY OF LEAVING GROUP-CONTAINING ORGANIC COMPOUND AND ORGANOSILICON COMPOUND NEW
発明の概要(英語) Provided is a method for preparing a coupled body represented by general formula (3), the coupled body being obtained by reacting a compound represented by general formula (1) and a compound represented by general formula (2) in the presence of an alcohol solvent, an inorganic base, and a palladium catalyst, the alcohol solvent having a site in which two adjacent carbon atoms each have a hydroxyl group. Ar1-X ··· (1) Ar2-Si(OR)3 ··· (2) Ar1-Ar2 ··· (3) [In the formulae, Ar1 represents an aryl group, etc., which may be substituted; X represents a leaving group such as a bromine atom; Ar2 represents an aryl group, etc., which may be substituted; and R represents an alkyl group having 1-5 carbon atoms.]
従来技術、競合技術の概要(英語) BACKGROUND ART
An organic compound having a leaving group of the organosilicon compounds and the coupling reaction, the reaction is generally referred to as hiyama (see Non-Patent Document 1). Hiyama reaction, and stable and nontoxic organic silicon compound is used, the liquid crystal material useful in the synthesis of drugs or the like (biaryl compounds and the like) of the coupling body can be obtained, also known as a useful reaction.
