Condensation of perfluoroalkyl iodides with unsaturated nitrogen compounds

Abstract

Condensation of enamines with perfluoroalkyl iodides yields α-perfluoroalkyl ketones. An intermediate charge-transfer complex between an iminium iodide and the perfluoroalkyl iodide has been detected. The reaction has been extended to α-alkoxy-enamines, ynamines, and pyrroles. It is rapid and uncatalysed for many simple enamines; others require u.v. light.
