Abstract

The synthesis and characterization of the novel sterically encumbered Ga(I) ligand GaCp*^Ph (1b) (Cp*^Ph = C ₅Me₄Ph) is presented. GaCp*^Ph reacts with the Pd(0) source Pd₂(dvds)₃ (dvds = tetramethyldivinyldisiloxane) to give the trinuclear cluster [Pd ₃(GaCp*^Ph)(μ²-GaCp *^Ph)(μ³-GaCp*^Ph)₂(dvds)] (2a). 2a is the first example of a Ga(I)-containing cluster with a potentially labile olefinic ligand. It was found that 2a is an intermediate in the formation of the dinuclear cluster [Pd₂(GaCp*^Ph) ₂(μ²-GaCp*^Ph)₃] (2b), which is formed on reaction of 2a with GaCp*^Ph. Both clusters were found to be labile toward GaCp*, AlCp*, or phosphines, giving substitution products in all cases.
