Cobalt-Catalyzed Hydroazidation of Olefins: Convenient Access to Alkyl Azides
Conversion of unactivated olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes by using 6 mol % Co(BF4).6H2O and ligand I, with 3 equiv of tosyl azide as the nitrogen source and simple silanes (e.g., PhSiH3, tetramethyldisiloxane). [on SciFinder (R)]
