intramolecularly coordinating dimethylaminomethyl group were prepared and treated with Li2PdCl4 or Pd(OAc)2. Highly selective cleavage of the aryl- CSi bond took place to give the corresponding arylpalladium complexes. Similar reactions were observed for benzylic trimethylsilyl compounds. The yields of the reactions with L2PdCl4 varied from 66 to 94%, but yields were > 90% when Pd(OAc)2 was used.

1-bromo-2-[(dimethylamino)methyl]naphthalene to [Pd(dba)2](dba = dibenzylideneacetone). Protection of C(3) with R = SiMe3 resulted in quantitative replacement of the SiMe3 group by palladium. Silicon–oxygen bond cleavage was observed when the substrate with R = OSiMe3 was treated with Pd(O2CMe)2. Palladium bis3-[(dimethylamino)methyl]-2-naphtholate} was obtained quantitatively.
