1,4-Bis(trimethylsilyl)-1,4-diaza-2,5-cyclohexadiene is an effective silyl transfer reagent towards the oxygen of nitrate coordinated to Cr(III) in a pincer complex. Two nitrate oxygens are removed to give the 17 valence electron octahedral complex (H₂L)Cr(NO₃)₂(NO). This is shown by a variety of spectroscopic methods, together with DFT, to be a Cr(I) complex with a linear CrNO unit. This work also identifies future applications of this reductive silylation process.

使用三价铬和Mashima试剂将硝酸盐选择性脱氧为亚硝酰基：还原甲硅烷基化†

1,4-双（三甲基甲硅烷基）-1,4-二氮杂-2,5-环己二烯是一种有效的甲硅烷基转移试剂，可与钳型络合物中与Cr（III）配位的硝酸氧反应。除去两个硝酸氧，得到17价电子八面体络合物（H ₂ L）Cr（NO ₃）₂（NO）。通过多种光谱方法以及DFT可以看出，这是具有线性CrNO单元的Cr（I）络合物。这项工作还确定了该还原甲硅烷基化工艺的未来应用。
