Title:
環状フッ素化カルボン酸オルトエステルおよび相応する化合物を合成するための方法
Document Type and Number:
Japanese Patent JP4262477
Kind Code:
B2
Abstract:
The invention relates to a process for the preparation of cyclic carboxylic acid orthoester fluorides in which a) at least one bis(alkylthio)carbenium salt is reacted with at least one organic compound containing at least two hydroxyl groups in the presence of at least one base, b) and subsequently, preferably in situ, the resultant thioorthoester is subjected to oxidative fluorodesulfurisation using a fluorinating agent and an oxidant to give the cyclic carboxylic acid orthoester fluoride.
