The T—silyl functionalized diamine-bis(ether-phosphine)ruthenium(II) complexes 1a(T°) — 1g(T°) (Scheme 1) were sol-gel processed in the presence of different amounts of the co-condensation agents CH3Si(OMe)3(Me—T°) and (MeO)2SiMe—(CH2)6—MeSi(OMe)2(D°—C6—D°) to produce a library of the interphase catalysts X1a — X1c, X2a — X2g, and X3a — X3g. Due to the remarkable electronic and steric effects of the co-ligands on the catalytic activity of such complexes, a series of aliphatic and aromatic diamines was selected. The new polymers were investigated by multinuclear CP/MAS solid-state NMR spectroscopy as well as by EXAFS, EDX, SEM, and BET methods. Selected interphase catalysts show high activities and selectivities in the hydrogenation of trans-4-phenyl-3-butene-2-one.
