标题:四乙铵氨基酸离子液体催化甘油与碳酸二甲酯的一锅法合成缩水甘油
摘要:制备了四种四乙铵氨基酸离子液体(taail),并将其用作从甘油和碳酸二甲酯容易地一锅法合成缩水甘油的催化剂.结果表明,与其他三种taail相比,哌嗪四乙铵([n 2222] [管])表现出最佳的催化活性,并在最佳条件下催化反应以达到96%的甘油转化率和79%的缩水甘油收率.而且,Dft计算结果进一步表明,这种优异的性能源自[n 2222] [管]中的羧基,这使得[n 2222] [管]能够有效地活化基板.

摘要:The present invention relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.

权利人:BAKER HUGHES OILFIELD OPERATIONS LLC
摘要:A method for direct synthesis of cyclic carbonates is achieved by reacting at least one epoxide with carbon dioxide in the presence of a choline catalyst, such as choline chloride, under mild conditions such as a temperature between about 25° C. to 150° C. and a pressure of from about atmospheric to 75 psi (0.52 MPa), in a cyclic carbonate solvent. The choline catalyst may be the only catalyst used, and a co-catalyst or hydrogen bond donor is not necessary. The concentration of choline catalyst in the solvent ranges from about 0.5 mol % to about 10 mol %, based on the epoxide.

标 题:Method for the synthesis of organopolysiloxanes containing carbonate groups
发明人：LERSCH PETER; WEITEMEYER CHRISTIAN
权利人:GOLDSCHMIDT AG TH
摘要:The invention relates to a method for the synthesis of organopoiysiloxanes of the general formula which contains cyclic carbonate groups. The inventive compounds have a high polarity, can be synthesized easily and, because of their compatibility with polar media, find use as additives for dispersion paints or lacquers and for coating the surfaces of pigments and fillers.
