Some pentafluoropyridine derivatives have been synthesized by the reaction of pentafluoropyridine with appropriate mono and bidentate nucleophile under ultrasonic irradiation. This new methodology provides good to excellent yields in short reaction times (25-120 min) at room temperature.
Synthesis and Structural Study of Bis-perfluoropyridyl Bridged by 1,4 and 1,2 Dihydropyridine. -The reaction of pentafluoropyridine (I) with 2-and 4-aminopyridines (II) and (IV) is described. The X-ray structures of (IIIa) and (V) are given. -(RANJBAR-KARIMI*, R.; MASHAK-SHOSHTARI, M.; HASHEMI-UDERJI, S.; KIA, R.; J.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
