چکیده
|
Fe3o4@sio2/aeptms/fe(otf)3 is a stable, effective, and magnetic nanocatalyst easily prepared and characterized using ft-ir spectroscopy, sem, tem, and vsm techniques. this nanocatalyst was successfully applied for trimethylsilylation of numerous alcohols (primary, secondary, and tertiary alcohols) with hexamethyldisilazane in 1 ml dichloromethane at room temperature to their corresponding trimethylsilyl (tms) ethers. quick response times and a simple reprocessing procedure are two fascinating advantages of this nanocatalyst. this catalyst protects alcohols at 1.5 min, and turn-over frequency (tof) values for the presented catalytic system have been estimated 833 h-1.
