1以有序介孔二氧化硅纳米粒子为可再生催化剂多组分一锅法合成4H-氧萘衍生物(英文)显示文摘A simple,efficient and environmentally benign protocol for the synthesis of 4H-chromene derivatives was developed using bio-compatible,neutral,and recoverable mesoporous silica nanoparticles as a catalyst.The 4H-chromene derivatives were obtained in excellent yields by three component reaction of an aldehyde or isatin,malononitrile,and cyclic 1,3-diketones in ethanol at 60℃.Yaghoub SARRAFI Ebrahim MEHRASBI Amir VAHID Mahmood TAJBAKHSH 2012催化学报2012,33,9:4
2Cu(II)salen配合物催化三组分偶联反应合成炔丙胺(英文)显示文摘A one pot three‐component coupling reaction of phenylacetylene, aldehyde, and amine derivatives in the presence of Cu(II) Salen complex as an efficient heterogeneous catalyst under solvent‐free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to excellent yields. This method provides a wide range of substrate applicability. The catalyst was reused several times without significant loss of its catalytic activity.Mahmood Tajbaksh Maryam Farhang Hamid Reza Mardani Rahman Hosseinzadeh Yaghoub Sarrafi 2013催化学报2013,34,12:2
3A mild,simple and efficient method for selectiveα-monobromination of 1,3-diketones and β-ketoesters using pyridinium bromochromate显示文摘Pyridinium bromochromate has been found to be a highly efficient and selective reagent for theα-monobromination of 1,3-diketones andβ-keto-esters in the absence of base,Lewis acid,or other catalyst.The products were formed in high to excellent yields under mild reaction conditions and in short reaction times.Yaghoub Sarrafi Marzieh Sadatshahabi Kamal Alimohammadi 2009Chinese Chemical Letters2009,20,4:2
4Microwave-assisted chemoselective copper-catalyzed amination of o-chloro and o-bromobenzoic acids using aromatic amines under solvent free conditions显示文摘用在微波照耀下面的 2-chloro 和 2-bromobenzoic 酸的有效胺化作用的 N 芳基 anthranilic 酸衍生物的催化铜的合成被报导。一些这个方法的优点是高 chemoselectivity,短反应时间,在对酸保护的需要的过程和消除上面的工作的容易。Yaghoub Sarrafi Manijeh Mohadeszadeh Kamal Alimohammadi 2009Chinese Chemical Letters2009,20,7:2
5An efficient and mild protocol for the synthesis of unsymmetrical ureas in the absence of catalyst and additives显示文摘A new practical method for the synthesis of unsymmetrical ureas was achieved by reaction of phenylurea with primary and secondary amines under neutral and mild condition in very good yields.The reaction took place in refluxing dioxane and does not require any catalyst or additives.Rahman Hosseinzadeh Yaghoub Sarrafi Nora Aghili 2010Chinese Chemical Letters2010,21,10:2
