Hydrosilylation of a wide group of alkynes (terminal and internal) with four structurally different silanes has been for the first time performed in supercritical CO₂ (scCO₂). The results clearly showed the advantages as well as the limitations of using of scCO₂ as a reaction and extraction medium for hydrosilylation of numerous alkynes with different functionality and volatility. Procedures for the synthesis and isolation of over forty silyl ethenes were described, among which more than twenty for the first time. Obtained products were fully characterized by ¹H, ¹³C, ²⁹Si NMR, GC–MS, and EA. Moreover, by X-ray crystallography, the molecular structures of (E)-3-(1,1,1,3,5,5,5-heptamethyltrisiloxan-3-yl)-2,5-dimethylhex-3-ene-2,5-diol (3n) and (E)-triethyl(2-(triphenylsilyl)vinyl)silane (12a) have been determined for the first time.

首次在超临界CO ₂（scCO ₂）中进行了多种炔烃与四种结构不同的硅烷的氢化硅烷化反应。结果清楚地表明，使用scCO ₂作为反应和萃取介质对许多具有不同官能度和挥发性的炔烃进行氢化硅烷化的优势和局限性。描述了合成和分离四十多种甲硅烷基乙烯的方法，其中首次超过二十种。获得的产物通过¹ H，¹³ C，²⁹ Si NMR，GC-MS和EA进行了充分表征。此外，通过X射线晶体学，（E）-3-（1,1,1,3,5,5,5-七甲基三硅氧烷-3-基）-2,5-二甲基己-3-烯-2,5-二醇（3n）和（E）-三乙基首次确定了（2-（三苯基甲硅烷基）乙烯基）硅烷（12a）。
