1A practical synthesis of bis(indolyl)methanes catalyzed by BF_3·Et_2O显示文摘Practical BF3Et2O catalyzed reactions between indoles and a series of carbonyl compounds at room temperature are described, which afford bis(indolyl)methanes with isolated yields up to 96%.Xia-Fei Xu Yan Xiong Xue-Ge Ling Xi-Mi Xie Jie Yuan Shu-Ting Zhang Zhong-Rong Song 2014Chinese Chemical Letters2014,25,3:7
2活性炭负载硫化锡纳米颗粒作为高效可重复使用Lewis酸催化剂催化三组分一锅法合成4H-吡喃[2,3-c]吡唑衍生物(英文)显示文摘Tin sulfide nanoparticles(SnS -NPs) were prepared in aqueous solution at room temperature on the surface of activated carbon(AC) and were investigated using field-emission scanning electron mi-croscopy(FE-SEM), transmission electron microscopy(TEM), X-ray diffraction, reflective ultravio-let-visible spectrophotometry, and spectrofluorimetry. Calculations based on the SEM and TEM images showed that the sizes of the SnS -NPs immobilized on the AC were 30–70 nm. The prepared nanocomposite was used as a heterogeneous Lewis acid catalyst for the three-components one-pot synthesis of 4H-pyrano[2,3-c]pyrazole derivatives in ethanol at 80 ℃. The reactions were efficiently performed in the presence of the prepared catalyst in short reaction times, and gave the desired products in high yields. This catalyst can be easily recovered by simple filtration and recycled up to eight consecutive times without significant loss of its efficiency.Nasir Iravani Mosadegh Keshavarz Hossein Ali Shojaeian Kish Rasool Parandvar 2015催化学报2015,36,4:4
3Synthesis of α-aminonitriles using silica-bonded N-propylpiperazine sulfamic acid as a recyclable catalyst显示文摘-Aminonitriles 经由一个一个壶被综合用象在房间温度的 recyclable 固体酸的结合硅石的 N-propylpiperazine sulfamic 酸(SBPPSA ) 的醛,胺,和 trimethylsilyl 氰化物的三部件的冷凝作用。SBPPSA 看了几乎相同的效率什么时候在连续反应跑使用了。Tahere Rahi Mojtaba Baghernejad Khodabakhsh Niknam 2012Chinese Chemical Letters2012,23,10:4
4Novel one-pot synthesis of 4H-chromene derivatives using amino functionalized silica gel catalyst显示文摘A simple, efficient, and environmentally benign method for the synthesis of 4H-chromene derivatives was developed using well ordered and recoverable amino functionalized silica gel as a base catalyst. The 4H-chromene derivatives were obtained in short time and excellent yield(87%–96%) by three component reaction of aldehydes, malononitrile and cyclic 1,3-diketones in water at 70 8C.Vijaykumar M.Joshi Rupali L.Magar Prashant B.Throat Sunil U.Tekale Bhagavan R.Patil Mangal P.Kale Rajendra P.Pawar 2014Chinese Chemical Letters2014,25,3:4
