catalyzed by an ionic liquid composite catalyst comprising a hydroxyl functionalized ionic liquid and an alkali metal salt under an aqueous condition to produce ethylene carbonate and ethylene glycol; (b) a hydrolysis step of reacting the reaction solution containing ethylene carbonate and the ionic liquid composite catalyst obtained in step (a) with water to produce ethylene glycol; (c) a purification step of dehydrating and refining ethylene glycol from the aqueous solution containing ethylene glycol and the catalyst produced in step (b). The present process has the following advantages: the catalyst has high activity, high suitability, and good stability, the reaction condition is wild, the conversion of ethylene oxide is high, the selectivity of ethylene glycol is high, and the process is simple.

(Cp*=pentamethylcyclopentadienyl) complexes. The reactivity of the new complexes has been studied with special attention to the transformations that deal with the alcohol functionality. The metal‐mediated intramolecular transformations allowed the formation of several products that resulted from the oxidation of the alcohols to aldehydes and esters. All the new complexes have been fully characterized,

ammonium ionicliquids at 100 °C gave corresponding phthalocyanines in moderate yield. Further the reaction of substituted phthalonitriles in the presence of transition-metal salts in ionicliquids gave the corresponding metallophthalocyanines. The 2-hydroxylethyl ammonium ionicliquids gave better yields of phthalocyanines than 2-hydroxylethyl imidazolium and nonhydroxyl functionalized ionicliquids. The
摘要 在任务特定的 2-羟乙基基咪唑鎓和铵离子液体中,取代的邻苯二甲腈在 100 °C 下四聚化,以中等产率得到相应的酞菁。此外,在过渡金属盐的存在下,取代的邻苯二甲腈在离子液体中的反应得到相应的金属酞菁。2-羟乙基铵离子液体比2-羟乙基咪唑鎓和非羟基官能化离子液体产生更好的酞菁收率。不同酞菁的分离和分离采用硅胶柱色谱法完成,产物采用多种光谱技术进行表征。图形概要

The synthesis and characterization of a series of new cationic gold(I) complexes with hydroxyl-functionalized N-heterocycliccarbene (NHC) ligands is described. They are valuable building blocks for further derivatization: as a first example, coupling with amino acids and a dipeptide, respectively, successfully results in amino acid and peptide conjugates that are hard to obtain by other synthetic
