标题:超亲电催化下 H/d 交换对失活芳基卤化物的全氘化
摘要:超亲电的硅/芳基离子被证明是高效的 H/d 交换促进剂,可用于缺电子芳基卤化物的彻底氘化.一些由此产生的过氘化芳基卤化物以前无法通过现有的氘标记程序获得.使用廉价的 C 6 D 6作为氘源,在环境反应条件下实现了优异的氘掺入程度.重要的是,即使在催化剂负载量减少 0.1 Mol% 的情况下,全氘化仍然不受影响.通过这种方法,可以制备昂贵的或非商业可得的NMR溶剂,例如1,2-二氯-和1,2-二氟苯.

标 题 :Polymerization of olefins
发明人：BROOKHART MAURICE S; JOHNSON LYNDA KAYE; KILLIAN CHRISTOPHER MOORE
权利人:DU PONT
摘要:Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear α-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected α-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected α-diimine nickel complexes with ethylene.

摘要:Copolymers of formula (I): n nwhere each A is S, Se or Câ•?C; each x is an integer from 1 to 4; each R1 is independently H, F, CN or a C 1 -C 20 linear or branched aliphatic group; Ar is one or more substituted or unsubstituted aromatic units; and, n is an integer 5 or greater, can be formed into films or membranes that are useful as active layers in organic electronic device, such as PV solar cells, providing high power conversion efficiencies and good thermal stability. Such copolymers may be synthesized from monomers of formula (II):n n nby Stille or Suzuki coupling reactions. Such monomers may be synthesized by a variation of the Pinner synthesis.
