Fe-Catalyzed three-component carboazidation of alkenes with alkanes and trimethylsilyl azide
Reported herein is a novel iron-catalyzed, DTBP-mediated carboazidation of alkenes using cycloalkanes, CH 2 Cl 2 , CHCl 3 and CCl 4 as alkylating reagents to generate electrophilic or nucleophilic alkyl radicals. Mechanistic studies suggested that the reaction proceeded via the addition of alkyl rad...

as alkylating reagents to generate electrophilic or nucleophilic alkyl radicals. Mechanistic studies suggested that the reaction proceeded
via
the addition of alkyl radicals to alkenes followed by an iron-mediated ligand transfer process. The reaction is unique as it is applicable not only to diversely functionalized electron rich alkenes, but also to electron-poor olefins to provide chain extended azides and γ-azido chloroalkanes in good to high yields.
