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