摘要:Supported onium salts used as initiators for the synthesis of polycarbonates by copolymerization of carbon dioxide with epoxides are described. Embodiments of the present disclosure describe initiators comprising an insoluble portion including an onium cation attached to an insoluble support; and an anion, wherein the anion is a counter-ion to the onium cation. Embodiments further describe methods of making polycarbonates using the initiator, methods of making initiators, and the like.

权利人:BEIJING TIENYI LUFU PHARMATECH CO LTD
摘要:The invention relates to intermediates useful in the preparation of halichondrin compounds, methods for preparing the same and use thereof, such as halichondrins, eribulin, or their analogs. The intermediates, the methods and use thereof are used for the synthesis of the C20-C26 fragment of halichondrin compounds. The raw materials in the synthetic route of the invention are cheap and easily obtained, the sources and the qualities of the raw materials are reliable. The choice of the methods useful in the synthesis of chiral central structures are based on the structural characteristics of the reactants, thus effectively improving the synthesis efficiency, reducing the difficulties and risks of product quality control, and avoiding the use of highly toxic and expensive organotin catalysts to significantly decrease costs and improve environmental friendliness.

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:New hexa-coordinate iron (II) complexes comprising compounds of formula (I) are described. These compounds comprise a tetradentate ligand with donor atoms comprising nitrogen and phosphorus. These complexes are shown for the first time to be useful catalysts for the hydrogenation of ketones, aldehydes, or imines to produce alcohols or amines, and the asymmetric hydrogenation of prochiral ketones or imines to produce non-racemic alcohols or amines. The source of the hydrogen can be hydrogen gas or a hydrogen-donating molecule such as isopropanol or hydrogen-donating mixture such as formic acid and an amine depending on the structure of the catalyst. In certain embodiments, the axial ligands on the catalyst comprise organonitrile ligands, carbonyl ligands, isonitrile ligands, or combinations thereof. The catalysts and the preparation thereof are disclosed. A reaction using phosphine and diamine precursors that is templated by the iron ion is the preferred route to the catalysts.
