In this contribution, two novel supported and non-supported ruthenium(II) complexes of type [RuCl₂(dppme)(NN)] where [dppme is H2C=C(CH ₂PPh₂)₂ and NN is N1-(3-(trimethoxysilyl) propyl)ethane-1,2-diamine] were prepared. The NN co-ligand caused release of one of the dppme ligands from [RuCl₂(dppme)₂] precursor to yield complex 1. The process of substitution of dppme by NN was monitored by ³¹P{¹H}-NMR. Taking advantage of the presence of trimethoxysilane group in the backbone of complex 1, polysiloxane xerogel counterpart, X1, was prepared via sol-gel immobilization using tetraethoxysilane as cross-linker. Both complexes 1 and X1 have been characterized via elemental analysis, CV and a number of spectroscopic techniques including FT-IR, ¹H-, ¹³C-, and ³¹P-NMR, and mass spectrometry. Importantly, carbonyl selective hydrogenation was successfully accomplished under mild conditions using complex 1 as a homogenous catalyst and X1 as a heterogeneous catalyst, respectively. © 2014 by the authors.
