title: Cooperative effect of two metals: CoPd(OAc)4-catalyzed C-H amination and aziridination.
abstract: The first Co/Pd-cocatalyzed intramolecular C-H amination and aziridination reactions were developed. Sulfamate esters were converted to oxathiazinanes by using CoPd(OAc)4 as catalyst and PhI(OAc)2 as oxidant. The mutual presence of both Co and Pd is crucial for the catalytic activity. This combination of two metals with simple acetate ligands provides an economical alternative to the Rh-catalyzed insertion of nitrenoids into C-H bonds.
