  重新审视苯乙烯酮的水合：一个违反直觉的结果

  摘要：

  在之前的工作中（Can. J. Chem. 1987, 65, 1719-1723 和 J. Am. Chem. Soc. 1995, 117, 9165-9171），发现重氮苯乙酮或苯基羟基环丙烯酮在水溶液中的闪光光解产生苯乙烯酮一种短暂的瞬态物质，其 λ 吸光度与 260 nm 一致，并以单指数动力学衰减。现在已经发现，在酸度区域 [H(+)] = 0.000 01 到 0.06 M，这种衰减之前有更快的吸光度上升，并且整体变化很好地符合双指数速率定律。对新数据的分析产生了速率曲线，其一般形状及其组成速率常数的数值，加上缓冲催化的形式，表明这种新发现的吸光度上升代表苯乙酸烯醇的酮化，并且随后的吸光度衰减代表向苯乙烯酮添加水。然而，该系统的化学性质要求乙烯酮水合以与吸光度变化相反的时间顺序先于烯醇酮化。然而，这个看似违反直觉的结果与控制中心物种在两步上升和衰减中的时间演化的速率定律是一致的，例如这里观察到的。

  Disclosed is a method for the combined synthesis of at least two vinylic monomers, at least one of which being an acrylic compound, comprising subjecting a monoconjgated alkene-1-carboxylic compound to reaction with a C2-C4 alkene under conditions of olefin cross-metathesis. The invention is particularly useful for extracting value from protein side streams. Upon protein hydrolysis, suitable amino acids (preferably phenylalanine or tyrosine) are subjected to reductive amination so as to form the corresponding alkene-1-carboxylic acid. Preferably after esterification and separation, this is used in cross-metathesis for the concomitant production of styrene resp. hydroxy styrene, and acrylates. The invention is applicable more widely, to the synthesis of olefins on the basis of carbohydrates, naturally occurring phenolic components, natural protein resources, or amino acids obtained from fermentations.

  本发明揭示了一种合成至少两种乙烯单体的方法，其中至少一种是丙烯酸类化合物，包括将一种单共轭烯烃-1-羧酸化合物与C2-C4烯烃在烯烃交叉烯烃交换反应条件下反应。该发明特别适用于从蛋白质副产物中提取价值。在蛋白水解后，适当的氨基酸（最好是苯丙氨酸或酪氨酸）经还原胺化反应得到相应的烯烃-1-羧酸。在酯化和分离后，这种产物可用于交叉烯烃反应，同时生产苯乙烯或羟基苯乙烯和丙烯酸酯。该发明更广泛地适用于基于碳水化合物、天然酚类成分、天然蛋白质资源或发酵得到的氨基酸的烯烃合成。

  A rubber-reinforced structure comprises a composite member comprising a resin member and a rubber member being directly bonded to the resin member without any adhesive, wherein the resin member and the rubber member form a tire. The composite member can be obtained by bringing a resin member into contact with an unvulcanized rubber composition in the following combination, and vulcanizing the unvulcanized rubber: (i) a combination of a rubber composition containing a radical-generating agent, and a resin composition containing a thermoplastic resin having at least two active atoms (a hydrogen atom or a sulfur atom) on the average per molecule, each atom having an orbital interaction energy coefficient S of not less than 0.006; (ii) a combination of a rubber composition containing a sulfur-containing vulcanizing agent or a radical-generating agent, and a resin composition containing a resin selected from a thermoplastic resin and a resin having a crosslinkable group; or (iii) a combination of a styrene-diene-series rubber composition containing a sulfur-containing vulcanizing agent or a rubber composition containing a radical-generating agent, and a resin composition containing a polyphenylene ether-series resin.

  Resist compositions comprising as the base resin a polymer using tert-amyloxystyrene as a reactive group which is decomposable under the action of an acid to increase solubility in alkali have advantages including a significantly enhanced contrast of alkali dissolution rate before and after exposure, a high sensitivity, and a high resolution in the baking temperature range of 100-110° C. which is unachievable with tert-butoxystyrene. The compositions are best suited as a chemically amplified resist material for micropatterning in the manufacture of VLSI.
