资源简介：
The unsymmetrically substituted disilyne, Dsi2iPrSiSiSiSiNpDsi2 (Np = CH2tBu) 2, was synthesized and characterized by X-ray crystallography to show a trans-bent structure with a silicon−silicon triple bond length of 2.0569(12) Å. The 29Si chemical shifts of the triply bonded silicon atoms of 2 are quite different, being observed at 62.6 ppm for the Dsi2iPrSi side and 106.3 ppm for the Dsi2NpSi side, indicating different hybridizations on the triply bonded silicon atoms at each site.
