1,4‐Bis(trimethylsilyl)‐1,4‐diaza‐2,5‐cyclohexadiene, 1, was tested as a reagent for the reductive silylation of various unsaturated functionalities, including N‐heterocycles, quinones, and other redox‐active moieties in addition to deoxygenation of main group oxides. Whereas most reactions tested are thermodynamically favorable, based on DFT calculations, a few do not occur, perhaps giving limited
1,4-双(三甲基甲硅烷基)-1,4-二氮杂-2-5-环己二烯1已作为试剂用于各种不饱和官能团(包括N-杂环,醌和其他氧化还原活性部分)的还原甲硅烷基化反应除了对主体氧化物进行脱氧。尽管根据DFT计算,测试的大多数反应在热力学上是有利的,但没有发生一些反应,也许对这种非常吸引人的还原过程的机理知之甚少。值得注意的是,还原性甲硅烷基化反应显示出强烈的溶剂依赖性,其中极性溶剂促进转化。
