Reaction of vinyl chloride with cationic palladium acyl complexes

Vinyl chloride (VC) reacts with the cationic Pd complexes [L2Pd(Me)(CO)][B(C6F5)4] (3a-d; L2 = Me2bipy, tBu2bipy, dppp, dmpe) and [L2Pd{C(=O)Me}(CO)][B(C6F5)4] (4a-d) by 2,1-insertion of L2Pd{C(=O)Me}(VC)+ intermediates to yield the O-chelated products [L2Pd{CHClCH2C(=O)Me}][B(C6F5)4 ] (5a-d). 5a-d were characterized by NMR spectroscopy, and the molecular structures of 5a and 5b·CH2Cl2 were determined by X-ray crystallography. The VC 2,1-insertion regiochemistry is favored in part because the alternative L2Pd{CH2CHClC(=O)Me}+ 1,2-insertion products would be destabilized by placement of the electron-withdrawing Cl and acyl substituents on the same carbon. In contrast to analogous nonhalogenated L2Pd{CHRCHR′C(=O)Me}+ species, 5a,c do not further react with CO, due to the stability of the chelate ring and the low migratory aptitude of the -CHClCH2C(=O)Me group.
