The recoverable nanomagnetic catalyst was manufactured based on thiourea modified magnetic hydroxyapatite. Magnetic hydroxyapatite (mHAp) as the inorganic-organic hybrid support was fabricated using co-precipitate condition and then modified via the covalently anchoring of 1-(3,5-bis(trifluoromethyl)phenyl-3-propyl)thiourea. The hybrid nano-catalyst has been identified by TEM, SEM, FTIR, BET, TGA, and XRD. This nanocatalyst appeared efficient and robust in the 1,4-addition reaction of TMSCN to α,β-unsaturated aromatic enones in excellent yields (85-96%) under mild reaction condition and simple work-up process. This recoverable organocatalyst has a great potential as an industrially viable and eco-safe catalyst.
