  The first η2-disilene–palladium complexes were synthesized using two different reactions; the reactions of bis(phosphine)dichloropalladiums with a 1,2-dilithiotetrakis(trialkylsilyl)disilane, which was prepared by the reaction of a stable tetrakis(trialkylsilyl)disilene with lithium (Method A) and the direct reactions of the bis(phosphine)dichloropalladiums with the stable disilene (Method B).

• 14-Electron Disilene Palladium Complex Having Strong π-Complex Character

  The first 14-electron disilene palladium complex eta2-[tetrakis(tert-butyldimethylsilyl)disilene](tricyclohexylphosphine)palladium (4) was synthesized. In the solid state, complex 4 has one tricyclohexylphosphine ligand bound unsymmetrically to the palladium center in regard to the eta2-disilene moiety. The elongation of the Si-Si bond length from that of the corresponding free disilene (3.2%) and the bent back angles of the disilene moiety (4.41 degrees and 9.65 degrees ) for 4 were much smaller than those for the corresponding 16-electron eta2-disilene complex (Me3P)2Pd[tetrakis(tert-butyldimethylsilyl)disilene] (4.6% and 27.2 degrees , respectively). Complex 4 is regarded as the complex having the strongest pi-complex character among the known disilene complexes. Highly symmetric NMR spectra were observed for 4; central Si1 and Si2 nuclei were equivalent and appeared as a doublet with 2J(29Si-31P) of 19 Hz, indicating facile flipping of the phosphine ligand in the Pd-Si-Si plane.

  The platinum silyl-substituted eta(2)-disilene complex (Me3P)(2)Pt[Si(SiMe2(t-Bu))(2)](2) (4) was synthesized by the reaction of cis-(Me3P)(2)PtCl2 (5) with 1,2-dilithiotrakis(tert-butyldimethylsilyl)disilane (6) in THF at -50 degreesC for 3 h. The X-ray structural analysis revealed that 4 can be regarded as a metalladisilacyclopropane with very weak pi-complex character.
