Abstract

The synthesis and structures of new 16-electron disilene palladium complexes with 2,6-dimethylphenyl isocyanide and phenyldimethylphosphine ligands [L 1 L 2 Pd((t-BuMe 2 Si) 2 SiSi(SiMe 2 Bu-t) 2 ), where L 1 = L 2 = PhMe 2 P; L 1 = (cyclohexyl) 3 P, L 2 = 2,6-dimethylphenyl isocyanide; L 1 = L 2 = 2,6-dimethylphenyl isocyanide] are described. Comparison of the X-ray structural parameters around the disilene moiety among these complexes and related bis(trimethylphosphine)(disilene)palladium and 14-electron (tricyclohexylphosphine)(disilene)palladium revealed that the π-complex character is sensitive to the residual ligands and increases with decreasing the strength of σ-donation from the ligands.
