Bronsted acidic ionic liquid based magnetic nanoparticles: A new promoter for the Biginelli synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones
Safari, Javad,Zarnegar, Zohre
, p. 358 - 365 (2014)
The Bronsted acidic ionic liquid 1-methyl-3-(3- trimethoxysilylpropyl) imidazolium hydrogen sulfate was immobilized on magnetic Fe3O4 nanoparticles (MNPs-IL-HSO4). The properties of the magnetic nanocatalyst were character
CoNiFe2O4@Silica-SO3H nanoparticles: New recyclable magnetic nanocatalyst for the one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones under solvent-free conditions
Karimian, Azam,Rad, Masoud Saadati,Mahdavi, Elham
, p. 1702 - 1714 (2020/09/07)
A useful and green synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones derivatives were achieved by one-pot cyclocondensation between substituted aryl aldehydes, diketone/ketoester, and urea/thiourea using magnetic CoNiFe2O4@Silica-
Efficient Catalytic Synthesis of 3,4-Dihydropyrimidin-2-ones/thiones via Little Acidic Ionic Liquid Combined with Rapid Heating Ways
Zhang, Guo-Ping,Tian, Da-Yu,Shi, Wang-Ming
, p. 2522 - 2531 (2018/09/29)
Catalytic synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones was efficiently promoted by as little as 2.5?mol% of Br?nsted acidic ionic liquid [(CH2)3SO3HMIM]HSO4 catalyst loading via rapid heating ways. Inter
