• General Description: 1-Hexyne, also known as Butylacetylene or n-Butylacetylene, is a terminal alkyne used in catalytic reactions such as selective hydrosilylation, where it reacts with triethylsilane in the presence of organoruthenium catalysts to yield specific products. The study demonstrates that its reactivity can be enhanced by tailored catalytic systems, such as biphenylene-bridged hybrid mesoporous materials, which improve catalytic efficiency due to higher metal loading and electron-donating effects.

Construction of an organoruthenium complex (-[biphRuCp]PF₆-) within a biphenylene-bridged inorganic-organic hybrid mesoporous material, and its catalytic activity in the selective hydrosilylation of 1-hexyne

10.1007/s11164-013-1460-1

The research investigates the synthesis and catalytic properties of an organoruthenium complex embedded within a biphenylene-bridged inorganic–organic hybrid mesoporous material (HMM–biph). The purpose is to explore the catalytic activity of this complex in the selective hydrosilylation of 1-hexyne with triethylsilane. The study concludes that the –[biphRuCp]PF6– complex within HMM–biph exhibits higher catalytic activity than a similar complex within phenylene-bridged HMM (HMM–phRuCp), attributed to the higher loading of the Ru complex in HMM–biph due to the electron-donating ability of biphenylene moieties. The research highlights the potential of tailored organic moieties in enhancing the catalytic performance of organometallic complexes embedded in hybrid mesoporous materials.
