Using NMR and ESI-MS to probe the mechanism of silane dehydrocoupling catalyzed by wilkinson's catalyst

The reaction of Wilkinson's catalyst Rh(PPh3)3Cl (1) with 1-2 equiv. of di-n-hexylsilane gives rise to a complex mixture of products, which has been analyzed by 31P{1H} NMR and shown to include the hydrido complex Rh(PPh3)3H (3). Continuous sampling of the 1:1 reaction mixture by ESI-MS provided time-dependent speciation that tracks the formation of 3 at the expense of the initial silane oxidative addition product [Rh(PPh3)2(Cl)(H){Si(nHex) 2H}] (2), the subsequent 1st order disappearance of 3, and the formation of other, minor side-products. Our results provide insight into established activity of 1 for catalytic dehydrocoupling of di-n-hexylsilane, and implicate complex 3 as the active species in this catalysis. The combination of 31P NMR and ESI-MS provides detailed insight into the dynamics of the activation of a secondary silaneby Rh(PPh3)3Cl, with strong evidence pointing to the role of Rh(PPh3)3H as the active catalyst for silane dehydrocoupling and to the deleterious effect of trace water in this system.
