Figure Abstract

Caption

The first iron-catalyzed phosphinoylazidation of alkenes under relatively mild reaction conditions affording compounds containing nitrogen and phosphorus is reported. This method is practically useful to deliver the azidophosphonates and requires relatively low loading of catalyst. Mechanistic studies confirmed the radical nature of the reaction and disclosed the unusually low activation energy 4.8 kcal/mol of radical azido group transfer from the azidyl iron(III) phthalocyanine species (PcFeIIIN3) to a benzylic radical rather than from the high-valent PcFeIV(N3)(Radical) species.
