标题:使用酰胺官能化的苯并咪唑鎓离子型离子液体轻松地将羧酸酯化
摘要:在这里,我们报告了一系列新的酰胺官能化的基于苯并咪唑鎓的离子型离子液体(dbimils)的合成,并评估了它们在三乙胺存在下对羧酸与烷基/烯丙基/芳基卤化物的感知酯化的功效.新系列dbimil中存在的酰胺基有望与羧酸形成氢键,这可以在温和条件下促进酯化反应,而无需添加任何催化剂或有机溶剂.已经提出了在这种新的il系列存在下增强催化活性的合理机制.从该反应中分离出的相应的烷基/烯丙基/芳基酯在简单萃取后具有高纯度,这消除了进一步纯化的必要性.

摘要:The present invention relates to regular shaped magnesium particles containing attrition resistant precursors and procatalysts thereof and processes for their synthesis and their use in the manufacture of polyolefins. More particularly, the present invention relates to a process for the synthesis of a said precursor particles which give highly active and improved surface area procatalysts for producing high bulk density polyolefin resins containing low fines and capable of incorporating high rubber content. In particular, the present invention relates to process for the synthesis of an attrition resistant precursors to prepare an attrition resistant Zeigler Natta procatalysts synthesized by using the precursors and to the polyolefin resin synthesized using the said procatalysts.

标题:Abietanes and methods of making and using the same

摘要:In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein is versatile polyene cyclization strategy that exploits conjugated β-ionyl derivatives. Photomediated disruption of the extended Ï€-system within these chromophores unveils a contra-thermodynamic polyene that engages in a Heck-type cyclization to afford [4.4.1]-propellanes. The connectivity of overbred polycycles generated from this process is controlled by the position of the requisite C-Halide bond. Thus, compared to conventional biomimetic polyene cyclization, this approach allows for complete control of regiochemistry and facilitates incorporation of both electron-rich and electron-deficient (hetero)aryl groups. This strategy was successfully applied to the total synthesis of abietanes such as, for example, taxodione and salviasperanol, two isomeric abietane-type diterpenes that previously could not be prepared along the same synthetic pathway.

摘要:A composition is provided, wherein the composition comprises a water-swellable, water insoluble polymer, a blend of a hydrophilic polymer and a complementary oligomer capable of hydrogen bonding to the hydrophilic polymer, and a whitening agent, preferably a peroxide. The composition finds utility as a tooth whitening composition and is applied to the teeth in need of whitening, and then removed when the degree of whitening has been achieved. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.
