Halogenating agent

摘要

wherein R<1> to R<4> are a substituted or unsubstituted, saturated or unsaturated alkyl group or a substituted or unsubstituted aryl group, and can be the same or different ; R<1> and R<2> or R<3> and R<4> can bond to form a ring including a nitrogen atom or a nitrogen atom and other hetero atoms ; or R<1> and R<3> can bond to form a ring including a nitrogen atom or a nitrogen atom and other hetero atoms, for example : a preparation process of the fluorinating agent and a process for preparing fluorine compounds by reacting various compounds with the fluorinating agent. The invention has also disclosed that the fluorinating agent is very effective for fluorinating oxygen containing functional compounds.
