• Ambident Reactivity of Phenolate Anions Revisited: A Quantitative Approach to Phenolate Reactivities

  reactions (C versus O attack) are opposite to the predictions by the principle of hard and soft acids and bases, we performed a comprehensive experimental and computational investigation of phenolate reactivities. Rate and equilibrium constants for the reactions of various phenolate ions with benzhydrylium ions (Aryl2CH+) and structurally related quinone methides have been determined photometrically in polar

  根据观察结果，酚酸反应（C与O攻击）的区域选择性与硬酸和软酸和碱的原理预测相反，我们对酚酸反应性进行了全面的实验和计算研究。各种酚酸根离子与二苯甲基铵离子（Aryl 2 CH +）和结构相关的醌甲基化物已在极性非质子传递溶剂中通过光度法测定。在SMD（MeCN）/ M06-2X / 6-31 + G（d，p）级别上进行的量子化学计算证实，在动力学控制的条件下，通常有利于O攻击，而在热力学控制的条件下，则有利于C攻击。例外是与强亲电试剂的扩散受限反应，该反应会产生由O和C攻击产生的产物混合物，以及在非极性溶剂中与金​​属醇盐的反应，其中强离子对阻止了氧气的攻击。刘易斯碱度（LB）和亲核性（N，s N）在这项工作中确定的酚盐参数可以用来预测它们与亲电试剂的反应是动力学还是热力学控制，以及速率是受活化限制还是受扩散限制。酚盐与碳正离子与吉布斯能量进行单电子转移反应所测得的速率常数的比较表明，这些反应是通过极性机理进行的。
• Preparation of 2,2'-Dihydroxytriphenylmethanes Using Metal Phenolates with Aromatic Aldehydes.

  DOI：10.1248/cpb.48.1810

  日期：——

  The reactions of oxophilic metal phenolates having electron-donating substituents (1a-c) with aromatic aldehydes (2, 3) were selectively condensed at the ortho-position of the starting phenol to afford 2,2'-dihydroxytriphenylmethanes (8-11). This method was also applicable to the preparation of bisphenols (12-17) starting with naphthaldehydes (4, 5) and pyridinecarboxaldehydes (6, 7), but in low yields

  具有给电子取代基（1a-c）的亲金属性金属酚盐与芳族醛（2，3）的反应在起始酚的邻位选择性缩合，得到2,2'-二羟基三苯基甲烷（8-11）。该方法也适用于以萘醛（4、5）和吡啶甲醛（6、7）为起始原料的双酚（12-17）的制备，但收率低。在这些醛（4-7）的情况下，通过超声处理可以获得令人满意的产率。
• MODIFIED HETEROPHASIC POLYOLEFIN COMPOSITION
  申请人：Milliken & Company

  公开（公告）日：2016-09-08

  A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, and a compatibilizing agent. The compatibilizing agent comprises (i) at least one tertiary carbon-hydrogen bond having a bond-dissociation energy of about 380 kJ/mol or less and (ii) at least one acyclic carbon-carbon double bond. A method of making a heterophasic polyolefin polymer composition comprises the steps of (a) providing a propylene polymer phase and an ethylene polymer phase, (b) providing a compatibilizing agent, and (c) mixing the propylene polymer phase, the ethylene polymer phase and the compatibilizing agent, in the presence of free carbon radicals. The compatibilizing agent reacts with propylene polymers and ethylene polymers thereby bonding propylene polymers to ethylene polymers.
