| Abstract: | A new route to organopalladium(IV) complexes is described, involving replacement of bromine in the 2,2′-bipyridyl complex PdBrMe2(CH2Ph)(by), by other halogen or pseudohalogen groups. 1H NMR studies of the decomposition of PDXMe2(CH2Ph)(bpy) in warm (CD3)2CO indicate that a selectivity in reductive elimination of alkanes occurs. to give ethane (X = Br, N3, NCS), or a mixture of ethane and ethylbenzene in ca. 9/1 ratio (X = F. Cl, I). The reductive elimination product azido(2,2′-bipyridyl)benzylpalladium(II) has been characterized by X-ray crystallography. |
