The synthesis and structures of new 16-electron disilene palladium complexes with 2,6-dimethylphenyl isocyanide and phenyldimethylphosphine ligands [L1L2Pd{(t-BuMe2Si)2SiSi(SiMe2Bu-t)2}, where L1= L2= PhMe2P; L1= (cyclohexyl)3P, L2= 2,6-dimethylphenyl isocyanide; L1= L2= 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. |
