CF2O結合を有する液晶の製造
Document Type and Number:
Japanese Patent JP5037999
Kind Code:
B2
Abstract:
The invention relates to a process for the preparation of compounds having at least one -CF2O- bridge in the molecule, which comprises initially reacting a bis(alkylthio)carbenium salt with a compound containing at least one hydroxyl group in the presence of a base followed by oxidative fluorination, preferably in situ, with a fluorinating agent and an oxidizing agent to form the compound having at least one -CF2O- bridge in the molecule.
