While stable in CH2Cl2, hexane or THF, in the presence of MeOH, self-promoted dimerization of the triarylphosphine-alkene 1, a ligand for Pd-catalyzed reactions, produced an unusual racemic bis(phosphine) 2 in high yield. The reaction of 2 with Pd(dba)2, followed by oxidative addition of p-IC6H4NO2, yielded a trans-chelated Pd(Ⅱ) aryl iodide complex.

A unified strategy toward the construction of the [5.7.6]tricyclic skeleton of liphagal is reported,featuring InCl3-mediated intramolecular Friedel-Crafts-type cyclization.
Palladium-catalyzed aerobic transformation has been one of the most challenging topics within organometallics chemistry. Recently, the corresponding methodology has been developed rapidly, involving alcohol oxidation, alkene oxidation, oxidative coupling and so on, which stimulated considerable interests in mechanistic investigation of the oxidation of Pd with O2 . This review summarizes most of the mechanistic studies on this topic during the past ten years. Moreover, the future of the mechanistic investigation for aerobic oxidation of Pd is also discussed.
