Cobalt-Catalyzed Hydroazidation of Olefins: Convenient Access to Alkyl Azides

Abstract

Conversion of olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes using 6 mol % Co(BF4).6H2O and ligand 1, with 3 equiv of TsN3 as nitrogen source and simple silanes (PhSiH3, TMDSO).
