Title:
LIQUID CRYSTAL COMPOUND, AND COMPOSITION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/225522
Kind Code:
A1
Abstract:
Provided are: a compound represented by general formula (i); and a composition and a liquid crystal display element which use said compound. The compound represented by general formula (i) is obtained by reacting a compound represented by general formula (i-r2) with a compound represented by general formula (i-r1) in the presence of a transition metal catalyst and a base to obtain a compound represented by general formula (i-r3), and subsequently inducing an intramolecular reaction by using the base to deprotonate the -Yi3-H in the compound represented by general formula (i-r3) to generate an anion. According to the present invention, a compound exhibiting a high Tni and a large Δε, and a composition and a liquid crystal display element which use said compound can be provided. Furthermore, a method for producing the compound and a production intermediate of the compound can also be provided.
