Highly efficient catalytic dimerization of styrenes via cationic Palladium(II) complexes

Article abstract of DOI:10.1002/adsc.201300864

A highly efficient head-to-tail dimerization of a styrene was developed using a cationic palladium(II)-catalyzed selective C-C bond forming reaction. The complex [AllylPd(PPh₃)]⁺OTf^-, which is believed to generate 'palladium hydride' (Pd-H), catalyzed the dimerization of various styrenes in excellent yields as single isomers. This Pd(II)-catalyzed reaction provides a new economical C-C bond forming method. Copyright
