4-AMINO-2,3,5,6-TETRAFLUOROPYRIDINE Chemical Properties,Usage,Production

Synthesis

In principle, ammonia could be used to allow indirect replacement of fluorine by hydrogen. Workers in this laboratory showed that pentafluoropyridine reacted with ammonia giving 4-aminotetrafluoropyridine.

Chemical Properties

white to light yellow crystal

General Description

4-Amino-2,3,5,6-tetrafluoropyridine is formed as C-H ′insertion′ product during reaction with 4-azido-2,3,5,6-tetrafluoropyridine.
