The cationic ruthenium(II) complex [(eta(5)-MeC5H4)Ru(eta(3)-PPh2CHCH2)(eta(1)-PPh2CHCH2)](+) (1) containing the hemilabile phosphaallyl ligand in two different coordination modes has been immobilized inside the pores of aluminated hexagonal mesoporous silica HMS(Si/Al = 40) by direct ion exchange method. This material was characterized by X-ray diffraction, thermogravimetric analysis, FTIR, solid state NMR (Si-29, Al-27), UV-Vis, and X-ray photoelectron spectroscopies. The textural properties were determined from nitrogen adsorption at 77 K. (1)/HMS(Si/Al = 40) was shown to be active and selective in the catalytic hydrogenation of phenylacetylene.
