Rhodium(III)-catalyzed C-H alkynylation of azomethine ylides under mild conditions.Org Biomol Chem. 2014 Dec 14; 12(46):9329-32.OB
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.
