title: Magnetically Retrievable Nanocomposite Based on Thiosemicarbazide-Formaldehyde Resin as a Versatile Nucleophilic Scavenger.
abstract: A magnetically retrievable nanocomposite was prepared by in situ polycondensation and entrapment of iron oxide nanoparticles. This material was found to be efficient in trapping excess electrophilic reagents such as carbonyl compounds, acid chlorides and isothiocyanates. Advantages of the new scavenger include facile preparation, high loading capacity, low cost, satisfactory swelling properties in polar solvents, and convenient magnetic recovery.
