Reaction of Trimethylsilylacetylenes with Antimony Pentafluoride under Matrix Isolation Conditions: Experimental and Computational Study

[摘要]：Reaction of trimethylsilylacetylenes Me3SiC CR with SbF5 in the solid State Was investigated using matrix isolation infrared spectroscopy and quantum-mechanical calculations. Two reaction pathways were detected Replacement of the trimethylsilyl group with I4SbC CR. Acteylenic neutral antimony acetylides. Acetyleme bond protonation produces silyl cation 6-R fully bridged for R = H and SiMe3 High total charges on the bridging SiMe3 group and low Me3Si-C bond orders to acetylenie moiety both calculated at the MP4(SDQ)/ 6-3H G(d p) level of theory. indicate high silyl cation character of these species
