A catalytic enantioselective domino Heck carbonylation reaction of o-iodoacrylanilides with phenylacetylenes or water has been developed using a Pd/(Cu) catalytic system containing a chiral diphosphine ligand L9, furnishing a wide array of chiral β-carbonylated 3,3-disubstituted oxindoles in high yields with up to 99 % ee values.

A palladium‐catalyzed cyclizative cross‐coupling of two o‐alkynylanilines to 2,3′‐bisindoles underaerobic oxidative conditions was developed. Mechanistic studies suggested that the two catalytic cycles, namely the formation of 3‐alkynylindoles 8 and their subsequent cyclization to bisindoles 5, are temporally separated. The aminopalladation of 3‐alkynylindoles 8 occurred only after all the N,N‐di
