Description
Hydrogen fluoride pyridine complex is used to prepare beta-fluoroamines via reaction with amino alcohols. As a fluorinating agent, is involved in the fluorination of 2,2-diary-1,3-dithiolanes. It is associated with nitrosonium tetrafluorborate to prepare gem-difluorides by reacting with ketoximes. It is also used to convert secondary and tertiary alcohols into their respective alkyl fluorides.
