Construction of a Novel Magnetic Nanomaterial, and its Utility as an Effectual Catalyst for the Fabrication of ۱, ۸-Dioxo-Octahydroxanthenes

At first, construction and characterization of a novel magnetic nanomaterial titled N۱-(Si-pr)-(N۱,N۱,N۴,N۴-tetramethylbenzene-۱,۴-diaminium) chloride dihydrogen phosphate grafted on Fe۳O۴@SiO۲ (STCDFS) have been described. The characterization has been accomplished by EDX, elemental mapping, FE-SEM, FT-IR, XRD, and VSM analyses. In continue, effectual and quick fabrication of ۱,۸-dioxo-octahydroxanthenes form aryl aldehydes and dimedone using STCDFS in solvent-free conditions has been reported. The xanthenes were acquired in ۹۲-۹۸% in ۵-۱۰ min. Moreover, the catalyst was reusable for one time without remarkable decrement in its performance.
