Sb–C Bond Cleavage Reaction on a Triruthenium Cluster and the Formation of a Bridging Phenylacyl Unit

Antimony–Carbon bond activation in a Pt(II) complex: The crystal structure of [Pt(9S3)(SbPh3)(Ph)](PF6)·CH3NO2

“…The cleavage of a phenyl group via Sb-C bond activation has been reported in several transition metal complexes containing triphenylstibine as a ligand [1][2][3][4][5][6][7][8]. Adams and co-workers have recently noted the formation of dirhenium complexes with rcoordinated phenyl rings formed from a coordinated SbPh 3 ligand [1].…”

“…Both the poor coordinating ability of the SbPh 3 ligands and the weak Sb-C bond strength play important roles in the process. We would note that this Sb-C bond cleavage in SbPh 3 is somewhat unusual in that it readily occurs in a simple, mononuclear complex at room temperature, without heating or the assistance of metalmetal bonds [1][2][3][4][5][6][7][8]. Neither of the two related complexes, [Pt(9S3)(SbPh 3 )(Cl)](PF 6 ) nor [Pt(9S3)(AsPh 3 ) 2 ](PF 6 ) 2 displays this reactivity [12].…”

“…Adams and co-workers have recently noted the formation of dirhenium complexes with rcoordinated phenyl rings formed from a coordinated SbPh 3 ligand [1]. Other examples of Sb-C bond cleavage of triphenylstibene in metal complexes include a triruthenium cluster [2], a triosmium cluster [3], a rhodium(II) dimer [4], hexaruthenium and osmium clusters [5], a stibine-gallium mononuclear complex [6], the formation of a nonanuclear organostiboxane cage via Sb-C bond cleavage [7], and carbon-antimony bond cleavage in a mononuclear Pd(II) complex [8]. Reid and co-workers have similarly reported carbon-antimony bond activation in bidentate Sb donor ligands which were coordinated to Rh(I) [9] while the Levason group reported photoactivation of a Sb-C bond in a binuclear Pd(II) complex [10].…”

“…A. Khan, H. A. Hafiz Malik, C. S. Yeap and H.-K. Fun Comment A large number of substituted derivatives, Ru 3 (CO) 12-n L n (L = group 15 ligand) have been reported (Bruce et al, 1985(Bruce et al, , 1988a. As part of our study on the substitution of transition metal-carbonyl clusters with mixed-ligand complexes, we have published several structures of triangulo-triruthenium-carbonyl clusters containing mixed P/As and P/Sb ligands (Shawkataly et al, 1998(Shawkataly et al, , 2004(Shawkataly et al, , 2010. Herein we report the synthesis and structure of the title compound.…”
