An organoruthenium complex (-[biphRuCp]PF6-; biph = -(C 6H4)2-, Cp = C5H5), constructed within a biphenylene-bridged inorganic-organic hybrid mesoporous material (HMM-biph) by use of a simple ligand-exchange reaction, has been used as a heterogeneous catalyst. UV-visible and X-ray absorption fine structure (XAFS) studies furnished evidence that the structure of the complex is closely similar to that of [(C6H6)RuCp]PF6, suggesting that the biphenylene moiety within HMM-biph directly coordinates the metal center of the organoruthenium complex. The -[biphRuCp]PF6- complex constructed within the HMM-biph (HMM-biphRuCp) catalyzes hydrosilylation of 1-hexyne with triethylsilane in a solid-gas heterogeneous system and gives α-vinylsilane as a main product. Moreover, HMM-biphRuCp has higher catalytic activity than the -[phRuCp]PF6- (ph = -C6H 4-) complex constructed within phenylene-bridged HMM (HMM-phRuCp). The high catalytic performance of HMM-biphRuCp can be attributed to the high loading of the HMM-biph with the Ru complex, because of the electron-donating ability of the biphenylene moieties.
