A series of three chiral, expanded six-membered NHC–palladium(II) complexes was prepared with successively increased sterical demand, while retaining natural d-(+)-camphor as a chiral motif. The catalysts showed different reaction profiles in the asymmetric, intramolecularα-arylation of amides. The molecular structure of two N-heterocyclic and one nitrogen acyclic carbene palladium isonitrile complex

A palladium catalyst derived from air-stable secondary phosphine oxide (1-Ad)(2)P(O)H enabled efficient intramolecular alpha-arylations of amides with aryl chlorides, which allowed for the synthesis of diversely substituted (aza)oxindoles.
