摘要：

A new series of fourteen triazolidine-3-thione derivatives (11 compounds) were synthesized via the reaction of aromatic aldehydes with thiosemicarbazide with samaria loaded fluorapatite, (Sm2O3/FAp) as catalyst in aqueous media. Fluoroapatite proved superior as support relative to hydroxyapatite in terms of improved yield and reduced reaction time. The new catalyst, Sm/FAp was characterized by various instrumental techniques including XRD, SEM, TEM and BET. Catalyst was easily separable and reusable for seven runs without any apparent loss of activity. The reported strategy has many benefits such as ease of preparation, green solvent, reduced reaction times, excellent product yields (92-97%) and operational simplicity. (C) 2017 Elsevier B.V.
