CATALYSED FLUORINATION OF CARBONYL COMPOUNDS

摘要

The present invention provides a method of substituting a carbonyl compound with fluorine at the alpha-position, comprising reaching the carbonyl compound with a fluorinating present of a metal-containing catalyst. The reaction results in replacement of a hydrogen atom by fluorine. The catalyst, which is used in a catalytically effective amount, is preferably a transition metal. In one class of methods the catalyst is a transition metal compound. In another class of methods, the catalyst is an elemental metal, in which case the carbonyl compound has an activating group attached to the carbon atom which is substituted by fluorine.
