| Summary: | 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. |
