The present work described the one-pot multicomponent synthesis of heterocyclic 3,4-dihydropyrimidin-2-(1H)-ones I [R1 = H, 2-Cl, 4-OH, etc.; R2 = OMe, OEt; X = O] and thiones II [X = S] (DHPMs) under via Biginelli reaction of benzaldehydes, alkyl acetates, urea/thiourea under solvent-free conditions by Sr2As2O7 nanocatalyst. Sr2As2O7 nanocatalyst was synthesized by solvothermal reactions at stoichiometric molar ratio. The characterizations of the as-prepared nanomaterials were performed by X-ray powder diffraction (XRPD) and fourier-transform IR (FTIR) techniques. According to Rietveld anal. data, it was found that reaction time had a considerable effect on crystal phase change from monoclinic to tetragonal crystal system. Field emission scanning electron microscope (FESEM) images showed that the morphol. of the obtained materials was changed by increasing the reaction time, from 24 to 120 h, from long-length rods to multigonal plates. Langmuir-Hinshelwood kinetic model revealed that the reactions followed a pseudo-first order kinetic model.3-Hydroxybenzaldehyde(cas: 100-83-4Recommanded Product: 3-Hydroxybenzaldehyde) was used in this study.
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Recommanded Product: 3-Hydroxybenzaldehyde
