Rhodium(iii)-catalyzed C–H alkynylation of azomethine ylides under mild conditions†
Abstract
Rh(III)-catalyzed efficient C–H alkynylation of azomethine imines with alkynylated hypervalent iodine is developed under mild conditions. A broad scope of azomethine imines and alkyne substrates is established. The azomethine acts as a masked aldehyde and circumvents its poor directing effect.
