an 
 iron - catalyzed diastereoselective intermolecular olefin 
 amino - oxygenation reaction is reported , which proceeds via 
 an iron - nitrenoid generated by the n  o bond cleavage of a functionalized 
 hydroxylamine . in this reaction , a bench - stable hydroxylamine derivative 
 is used as the amination reagent and oxidant . 
 this method tolerates 
 a range of synthetically valuable substrates that have been all incompatible 
 with existing amino - oxygenation methods . 
 it can also provide amino 
 alcohol derivatives with regio- and stereochemical arrays complementary 
 to known amino - oxygenation methods .
