Fe_۳O_۴@SiO_۲/AEPTMS/Fe(OTf)_۳: An efficient superparamagnetic nanocatalyst for the protecting of alcohols

Fe۳O۴@SiO۲/AEPTMS/Fe(OTf)۳ 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 ۱ 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 ۱.۵ min, and turn-over frequency (TOF) values for the presented catalytic system have been estimated ۸۳۳ h-۱.
