Abstract
High Resolution Image Download MS PowerPoint Slide Unactivated olefins are converted to alkyl azides with bench-stable NaN 3 in the presence of FeCl 3 ·6H 2 O under blue-light irradiation. The products are obtained with anti-Markovnikov selectivity, and the reaction can be performed under mild ambient conditions in the presence of air and moisture. The transformation displays broad functional group tolerance, which renders it suitable for functionalization of complex molecules. Mechanistic investigations are conducted to provide insight into the hydroazidation reaction and reveal the role of water from the iron hydrate as the H atom source.
