A palladium-catalyzed cross-coupling reaction of 2-alkylphenyl bromides with biphenylene has been developed. The reactions formed eight-membered carbocycles through C(sp3)-H activation and the formation of two C-C bonds, and the chiral products were obtai

The 1,4-palladium shift strategy allows the functionalization of remote C?H bonds that are difficult to reach directly. Reported here is a domino reaction proceeding by C(sp3)?H activation, 1,4-palladium shift, and amino- or alkoxycarbonylation, which generates a variety of amides and esters bearing a quaternary β-carbon atom. Mechanistic studies showed that the aminocarbonylation of the σ-alkylpalladium intermediate arising from the palladium shift is fast using PPh3 as the ligand, and leads to the amide rather than the previously reported indanone product.

Copper-catalyzed domino coupling reaction: An efficient method to synthesize oxindoles
Hsieh, Jen-Chieh,Cheng, An-Yi,Fu, Jun-Hao,Kang, Ting-Wei
supporting information; experimental part, p. 6404 - 6409 (2012/09/05)
An efficient and novel procedure for a copper catalyzed domino coupling reaction has been developed, which afforded various oxindoles in good to excellent yields with tolerance of various substituents. In addition, this method could be applied to synthesize horsfiline and coerulescine in few steps with high total yields. The Royal Society of Chemistry 2012.
