除此之外,使用其他空间位阻大的取代基修饰氮原子也可提高Si-N键的键能,增强硅烷试剂的稳定性。于是,他们合成了1-金刚烷氨基取代的三(三甲基硅基)硅烷3,3可在光氧化还原催化剂的作用下发生SET得到氮中心自由基5,随后通过氮杂Brook重排形成α-氨基硅中心自由基,进而与非活化氯代烷烃作用完成后续转化。 非活化氯代...

In this paper, using the above structure, we prove the existence of an ${\cal N}_c$-covering group for a nilpotent product of a family of cyclic groups. We also present a structure for the ${\cal N}_c$-covering group.关键词:...

The present experiment studied the growth, morphology and C/N metabolism of a representative submersed macrophyte, Vallisneria natans, in response to various light regimes (2.8%, 7.1%, 17.1%, and 39.5% ambient light intensity) over a period of 12 months. The results showed that the total ...
Table 3. Evaluation of the Functional-Group Tolerance of the Silylation of Secondary C−H Bonds. (图片来源:J. Am. Chem. Soc.) 接下来作者探究了C-H硅烷化反应的机理。首先,分别测量了非氘化硅醚8和氘化和硅醚8-d4的反应初始速率(Scheme 3)。动力学同位素效应值为2.2,表明反应中C-H键的断裂是...
