  苯乙酸芳基酯与仲胺在 MeCN 中的反应。乙烯酮形成消除和 E2 和 E1cb 并发机制中的结构 - 反应性关系

  摘要：

  已经对 MeCN 中由 R2NH 促进的芳基乙酸 1 和 2 的芳基酯的消除反应进行了动力学研究。反应是二级反应，表现出 β = 0.44−0.84，|βlg| = 0.41−0.50，ρH = 2.0−3.6。布朗斯台德β和|βlg| β-芳基取代基的吸电子能力降低。Hammett ρH 值几乎保持不变，但 |βlg| 值随着基础强度变弱而增加。随着离去基团从 4-硝基苯氧基变为 2,4-二硝基苯氧基，ρH 和 β 均降低。结果与 E2 机制和具有对应于质子转移的大水平分量的反应坐标一致。当碱-溶剂系统从 R2NH-MeCN 变为 R2NH/R2NH2+-70 mol % MeCN(aq) 时，Bronsted β、ρH 和 |βlg| 减少。最后，

  Volatility of some aromatic nitrosubstituted plasticizers for polymers

  摘要：

  Nine derivatives of nitrophthalic acids and nitrophenols were synthesized as potential plasticizers for polymers and structurally characterized by H-1 NMR and elemental analysis. The time dependences of the weight loss for the nitro derivatives synthesized and for commercial plasticizers (dibutyl phthalate and dioctyl phthalate) were obtained by gravimetric method at 100AC, and their volatilities and dipole moments were calculated. The resultant nitroplasticizers are considerably less volatile than dibutyl phthalate. Low volatility is associated not so much with high molecular weight as with high polarity. The nitroplasticizers are well compatible with cellulose esters and exhibit low rates of migration from polymer films.

  An embodiment of the invention is a water soluble chain-extended polyamine product made by a process comprising reacting a multi-arm polyether amine with a bifunctional crosslinker of the formula: X 1 —R—X 2 . Another embodiment is a water soluble chain-extended polyamine product made by a process comprising reacting a multi-arm polyether having at least three arms and three electrophilic endgroups with a primary diamine crosslinker of the formula: NH 2 —R 2 —NH 2 , followed by treating of the chain-extended product so as to convert the remaining electrophilic endgroups to amine endgroups. Crosslinking of the chain-extended polyamine products with an oxidized polysaccharide provides useful tissue adhesives with modified elasticity, that provides greater compliance to underlying tissue, and improved stability in aqueous environments.
