Shown is a method for producing an N-silylaminoalkylsilane compound. The N-silylaminoalkylsilane compound is produced by allowing an aminoalkylsilane compound to react with a monochlorosilane compound in the presence of a tertiary amine compound having an acid dissociation constant (pKa) of 7 or more and a polar surface area (PSA) of 12 Å
2
or more. The aminoalkylsilane compound is a compound represented by formula (1), for example. In formula (1), R
1
is alkyl having 1 to 5 carbons; R
2
is hydrogen, phenyl or 2-aminoethyl; m is 1, 2, 3, 4 or 5; and n is 0, 1 or 2. A reaction is as described in (ZZ) below, for example.
Abstract This work reports the synthesis and structuralcharacterization of a new adenine based organosilicon nucleobase using an efficient and biocompatible Click approach. Synthetic procedure included the preparation of a new N -acetylinic linked propyl silatrane 3 whose structure was confirmed through Single crystal X-ray crystallography. The designed silatrane L is found to be highly selective
摘要这项工作报告了一种新型的基于腺嘌呤的有机硅核碱基的合成和结构表征,该方法使用了一种有效且生物相容的Click方法。合成步骤包括制备新的N-乙酰基连接的丙基甲硅烷基3,其结构已通过单晶X射线晶体学确认。发现设计的硅橡胶L具有高度的选择性和灵敏度,可检测到从无色到淡橙色的颜色变化的Cu 2+。L + Cu 2+的化学计量比通过Job's Plot获得1:1。在较宽的pH范围内研究了铜离子与化学传感器的结合,结果表明该传感器在6–9的生理范围内工作良好。此外,发现在添加EDTA时Cu 2+的感测是可逆的。这些结果扩大了比色探针领域中基于腺嘌呤的衍生物的范围。通过各种光谱技术[IR,NMR(1 H,13 C)和质谱]和元素分析成功地表征了新合成的硅杂环烷3和受体L。
This invention relates to hydrolysable silanes useful in the modification of elastomers, and as coupling agents for diene elastomer compositions containing a filler. In particular the invention relates to novel hydrolysable silanes containing a tertiary amine group and an ether or thioether linkage.
