, p. 1321 - 1330 (1997)
A new homochiral dimeric ortho-palladated complex bearing a bulky tert-butyl substituent at the carbon stereocenter was synthesized from optically active N,N-dimethyl-α-tert-butylbenzylamine. Regioselective activation of only the aromatic C-H bond was sho

(Chemical Equation Presented) Bring on the big cats: New, C 2-symmetric bulky N-heterocyclic carbene ligands bring major improvements in the palladium-catalyzed asymmetric intramolecular α-arylation of amides to give oxindoles (see picture, dba=trans,trans- dibenzylideneacetone), which are formed in high yield and excellent enantiomeric purity.

ortho-Palladation of a sterically crowded primary benzylamine, α- phenylneopentylamine, was accomplished in a moderate yield of 50% in the reaction with the weakest of palladation agents (Li2PdCl4) under very mild conditions, due to
