Abstract The generation of trifluoroacetonitrile (1) under mild conditions and controlled rates from easily accessible starting materials is described. Dehydration of trifluoroacetamide (2) with trifluoroacetic anhydride in pyridine generates trifluoroacetonitrile at ambient temperatures. As the trifluoroacetonitrile is formed, it distills out of the pyridine reaction mixture and is bubbled into a
