PROBLEM TO BE SOLVED: To provide a method by which a compound having at least one -CF<SB>2</SB>O- bridge in the molecule and useful as a liquid crystal compound is produced in a satisfactory rate of reaction in excellent yield. SOLUTION: The compound having at least the one -CF<SB>2</SB>O- bridge in the molecule is formed by initially reacting a bis(alkylthio)carbenium salt with a compound containing at least one hydroxy group in the presence of a base and then, preferably in situ, oxidatively fluorinating the resultant compound with a fluorinating agent and an oxidizing agent. Thereby, the compound having at least the one -CF<SB>2</SB>O- bridge in the molecule is formed. COPYRIGHT: (C)2008,JPO&INPIT |
