1Silica supported perchloric acid(HClO_4-SiO_2):A mild,reusable and highly efficient heterogeneous catalyst for the synthesis of amidoalkyl naphthols显示文摘An efficient and direct procedure has been developed for the preparation of amidoalkyl naphthols by a one-pot condensation of aryl aldehydes,2-naphthol and urea or amides,in the presence of HClO_4-SiO_2 as a heterogeneous catalyst.The reactions were carried out under reflux and solvent-free conditions.The present methodology offers several advantages such as excellent yields, simple procedure,easy work-up and ecofriendly reaction condition.The catalyst is easily prepared,stable,reusable and efficient under the reaction conditions.Gholam Hossein Mahdavinia Mohammad A.Bigdeli Majid M.Heravi 2008Chinese Chemical Letters2008,19,10:7
2A series of 1,8-dioxooctahydroxanthenes are prepared using trichloroisocyanuric acid显示文摘一系列芳香的醛作为催化剂用 trichloroisocyanuric 酸(TCCA ) 被上交到 3,3,6,6-tetramethyl-9-aryl-1,8-dioxooctahydroxanthene 衍生物。Mohammad A.Bigdeli Firouzeh Nemati Gholam Hossein Mahdavinia Hamideh Doostmohammadi 2009Chinese Chemical Letters2009,20,11:2
3Wet cyanuric chloride promoted efficient synthesis of amidoalkyl naphthols under solvent-free conditions显示文摘一个有效、直接的过程被芳基醛, 2 萘粉和脲或酰胺的一个一个壶冷凝作用为氨基烷基萘粉的准备开发了,面对象催化剂的湿氰尿酸的氯化物(wet-TCT ) 。反应在没有溶剂的媒介下面被执行。现在的方法论提供象优秀收益,简单过程和 eco 友好的反应状况那样的几个优点。Gholam Hossein Mahdavinia Mohammad A.Bigdeli 2009Chinese Chemical Letters2009,20,4:2
4Covalently anchored sulfonic acid on silica gel(SiO_2-R-SO_3H)as an efficient and reusable heterogeneous catalyst for the one-pot synthesis of 1,8-dioxooctahydroxanthenes under solvent-free conditions显示文摘A highly efficient one-pot synthesis of 1,8-dioxooctahydroxanthenes under solvent-free conditions catalyzed by sulfonic acid covalently anchored onto the surface of silica gel is reported.All types of aldehydes,including aromatic,unsaturated,and heterocyclic,are used.The silica gel/sulfonic acid catalyst(SiO_2-R-SO_3H)is completely heterogeneous and can be recycled.Gholam Hossein Mahdavinia Mohammad A.Bigdeli Yaser Saeidi Hayeniaz 2009Chinese Chemical Letters2009,20,5:2
