摘要: A magnetic nanoparticle conjugated mesoporous nanocatalyst (Fe(3)O(4)@mesoporous SBA-15) with a high surface area has been synthesized by chemical conjugation of magnetite (Fe(3)O(4)) nanoparticles functionalized SBA-15. Functionalized SBA-15 containing carboxyl and amino groups was via the thiol-ene click reaction cysteine hydrochloride vinyl The catalytic activity robust, safe magnetically recoverable Fe(3)O(4)@mesoporous evaluated in Biginelli under mild conditions for synthesis diverse range 3,4-dihydropyrimidin-2(1H)-ones. separation reuse were simple, effective economical.
