Abstract
The reaction of silica-supported bis(allyl)rhodium, (SiO)(SiOX(Rh(η3-C3H5)21(X = H, Si) with PMe3 followed by H2 yields [RhH2(PMe3)4]+, 2, which is characterised by IR, solid-state 31P NMR and elemental analyses and extracted quantitatively from the surface by ion-exchange with Bun4NCl in nitromethane; the counterion of 2 is presumed to be a siloxy group [SiO]– of the silica surface.
