We disclose herein a directing group-assisted nickel-catalyzed intermolecular C(sp3)–H amidation using organic azides as nitrene precursors. With the installation of an electronically tailored dire...

We describe a protocol for cobalt-catalyzed hydrosilylation of 3-alkynes with accompanying π-bond migration. Mechanistic studies indicate that (i) cobalt(I)-hydride bearing a bulky bisphosphine lig...

Described herein is the Ir-catalyzed enantioselective access to chiral spirolactam products via the nitrenoid transfer to aromatic ipso-carbons. The key strategy for precise stereocontrol is to enhance the secondary attractive and repulsive interacti

Two mechanistic pathways, that is, electrocyclization and electrophilic aromatic substitution, are operative in most intramolecular C-H amination reactions proceeding by metal nitrenoid catalysis. Reported here is an alternative mechanistic scaffold

Guiding nitrenes away from a migration Nitrogen conventionally shares its electrons in three bonds with one or more partners. A singly bonded nitrogen, or nitrene, is exceptionally reactive and can insert itself into normally inert C–H bonds. If th
