标题:在温和条件下使用氮丙啶催化转化co 2的任务特定离子液体的设计
摘要:开发了一系列聚乙二醇(peg)-官能化的离子液体(il),作为可回收和有效的催化剂,用于从氮丙啶和co 2选择性合成5-芳基-2-恶唑烷酮,而无需添加任何有机溶剂或添加剂.特别地,当使用brdbnpeg 150 Dbnbr(dbn:1,5-二氮杂双环[4.3.0] Non-5-Ene)作为催化剂时,恶唑烷酮的收率高,化学选择性和区域选择性高,这可能是由于活化了通过peg主链中的醚键产生co 2,并通过离域阳离子brdbnpeg 150 Dbn +稳定氮丙啶的开环物质.此外,该催化剂可以重复使用超过四个连续周期,而不会明显丧失催化活性和选择性.还详细研究了催化剂结构和各种反应参数对催化剂性能的影响.结果表明,该催化剂对各种氮丙啶均能很好地产生相应的恶唑烷酮,并具有非常好的收率和极好的区域选择性.因此,这种无溶剂的方法因此可以代表将il 2催化的co 2转化为增值化学品的环保方法.

标题:Synthesis of diaza crown ethers
发明人：CHAMPION DONALD H; SPERANZA GEORGE P; RENKEN TERRY L

摘要:Poly(ethyleneoxy)amines, such as those having the structure: H2N-(CH2)a-(OCH2CH2)b-NH-(CH2CH2O)c-(CH2)d-R where a and d are independently 2 to 3; b and c are independently 1 to 4 and R is -OH or -NH2, may be reacted over a transition metal catalyst such as one containing nickel to produce diaza crown ethers, such as, for example 4,13-diaza-18-crown-6. If the poly(ethyleneoxy)amine is a diamine having a hydroxyl group of the above formula, the reaction may produce the corresponding triamine in the presence of ammonia. These triamines also readily form diaza crown ethers at near complete conversions simply from nickel, platinum, and palladium metal catalysts alone or with other transition metals such as copper and/or chromium. The process avoids tedious, multiple step procedures and the high dilutions that accompany prior diaza crown ether preparations.

标 题:Beaded and Cross-Linked Poly(Aminoalkylene)Matrix and Uses Thereof
发明人：GAVELIN PATRIK; PEHR-REHNBERG NICOLA; JOHANNSEN IB
权利人:VERSAMATRIX AS
摘要:The present invention relates to the synthesis of a beaded and cross-linked, high loading capacity polymer for solid phase synthesis, purification of reaction mixtures, chromatographic separation procedures, and the like. The invention can thus be used for the isolation of molecular entities having an affinity for the polymer beads or a chemical entity attached thereto. The beaded polymer matrix can be formed by cross-linking an optionally substituted poly(aminoalkylene), under inverse suspension or inverse emulsion polymerisation conditions, with a cross-linking unit of functionality ≧2.
