The reactions of isobutyl(isopropoxy)silyl bromides i-Bun(i-PrO)3−nSiBr (n = 0–3) with H2S in the presence of Et3N yield the corresponding silanethiols, i-Bun(i-PrO)3−nSiSH. The transition energy σ → σ★ and the IP of SiS bond, as well as the first IP of sulphur lone pairs do not change significantly as the number of electronegative i-PrO groups is varied. The geminal anomeric effects seems to be the
在Et 3 N存在下,异丁基(异丙氧基)甲硅烷基溴i-Bu n(i-PrO)3 - n SiBr(n = 0-3)与H 2 S反应生成相应的硅烷硫醇i-Bu n( i-PrO)3 - n SiSH。随着电子负性i-PrO基团数目的变化,跃迁能σ→σ ★和SiS键的IP以及硫孤对的第一个IP不会显着变化。双异头效应似乎是i-Bu(i-PrO)2 SiSH和i-Bu(i-PrO)2 SiH反应性提高的原因。
