Sayin, SerkanYilmaz, Mustafa2020-03-262020-03-2620140040-4020https://dx.doi.org/10.1016/j.tet.2014.06.034https://hdl.handle.net/20.500.12395/30653Three magnetically recoverable Bronsted acidic calix[n]arene derivatives were successfully constructed by immobilizing calix[n]arene sulfonic acids onto silica-coated magnetic nanoparticles, a process, which allows calix[n]arene derivatives to acquire magnetic properties. All of the magnetically recoverable Bronsted acidic calix[n]arenes efficiently catalyze the coupling of electron-rich arenes with some alcohols in water. After separation and recovery from the reaction mixture by a simple magnet, these Bronsted acidic calix[n]arenes can be recycled many times without losing their catalytic activity.
