摘要:我们研究了在303-323 K时丙-1-醇和丙-2-醇对芳烃磺酰氯的溶剂分解机理.动力学曲线适合一阶动力学.反应性随供电子取代基的增加而增加.芳烃磺酰氯的邻烷基取代衍生物显示出增加的反应性,但这种"正向"邻效应的起源仍不清楚.可能,邻位甲基限制了绕c键的旋转,从而促进了亲核试剂的攻击.就亲核性空间效应而言,未发现丙-1-醇和丙-2-醇的相关反应性变化.所有底物的等动力学关系的存在表明该系列的单一机制.两种醇中所有底物的溶剂分解反应均显示等速温度(t Iso)接近工作温度范围,这表明该过程受到次级反应性因素的影响,该因素可能是ts中的空间性质.溶剂化在该反应中起重要作用,调节反应性.在一些情况下,存在吨-Bu代替我在对位位置导致第一溶剂化壳的变化,从而增加了反应能量(约1 Kj.mol-1).所得结果表明,芳烃磺酰氯对丙-1-醇和丙-2-醇的溶剂化动力学机制与在meoh和etoh中相同,其中双分子亲核取代(s

摘要:This invention relates to lysine isotopologues of Formulas I and 1-A, as described herein, and processes for synthesizing the same and derivatives and intermediates involved therein. In one aspect, described herein is a chemical compound comprising an isotopically labeled analog, i.e., an isotopologue of a standard or naturally occurring lysine. The lysine isotopologue is synthetically formed to have stable isotopes of elements incorporated at selected positions. As such, the lysine isotopologue has a molecular mass different from the mass of a standard or naturally occurring lysine.
