1,7,8-TRIFLUORONAPHTHALENE-2-NAPHTHOL, AND METHODS FOR PRODUCING LIQUID CRYSTAL COMPOUNDS USING SAME

摘要

The present invention provides 1,7,8-trifluoro-2-naphthol and a derivative thereof as intermediates for efficiently producing a trifluoronaphthalene liquid crystal material. A method for efficiently producing a trifluoronaphthalene liquid crystal material using such intermediates is also disclosed. A naphthol derivative having the following general formula (I) is disclosed. A method for producing a trifluoronaphthalene compound having the following general formula (IV), (VI) or (VIII) using the naphthol derivative as a raw material is also disclosed.
