متن کاملSiO2-BaCl2 as a Highly Efficient and Reusable Heterogeneous Catalyst for the One-pot Synthesis of 3,4-dihydropyrimidin-2-(1H)- one/thione Derivatives Under Solvent-free Conditions
An efficient protocol for the synthesis of 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives via multi-component coupling reaction of aromatic aldehydes, β-ketoester and urea or thiourea under solvent-free conditions using Silica Supported Barium Chloride as a catalyst is described. All prepared compounds with melting points, IR,1H NMR and 13C NMR were identified. High yields, mild conditi...
متن کاملNew method for preparation of MWCNT-SO3H as an efficient and reusable catalyst for the solvent-free synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones
Multiwalled carbon nanotubes (MWCNTs) have been functionalized with -SO3H groups using new three steps chemical routes. Firstly, OH groups have been attached to CNT surfaces through a radical reaction. The second step involves converting the hydroxyl groups into the oxide one and last step included the attachment of –SO3H groups on the MWCNTs surfaces in the presence of 1-butyl-3-methyl imidazo...
