摘要：

Synthetic routes to neopentyl and trimethylsilylmethyl complexes of Pd(II) are reported, Pd(CH2EMe3)Ph(tmeda) [E = C (1), Si (3); tmeda = N,N,N',N'-tetramethylethylenediamine] and Pd(CH2EMe3)Ph(bpy) [E = C (2), Si (4); bpy = 2,2'-bipyridine]. Complexes I and 3 are formed on the reaction of PdIPh(tmeda) with LiCH2EMe3, and they react with bpy to give 2 and 4. Oxidative addition reactions of 8-(bromomethyl)quinoline (mqBr) with Pd(CH2EMe3)Ph(bpy) result in the formation of octahedral Pd(IV) complexes [Pd(mq)(CH2EMC3)Ph(bpy)]Br [E = C (5), Si (6)]. An X-ray structural analysis for 5, the first example of a stable cationic arylpalladium(IV) complex, shows a fac-PdC3N3 configuration with the neopentyl group trans to the quinoline nitrogen donor atom.
