Synthesis, fluorescence properties and Zn ²⁺ recognition of 4-Aryl-6-phenylpyrimidin-2(1H)-one

Abstract

4-Aryl-6-phenylpyrimidin-2(1H)-ones were synthesised via a three-component one-pot cyclocondensation of aromatic aldehyde, acetophenone and urea catalysed by 0.2 ml (0.024 mol%) of concentration HCI in ionic liquid [BMIM][BF 4 ]. The fluorescence properties of product and partial products’ efficient sensing of zinc ion were studied in detail. The structure of 4,6-diphenylpyrimidin-2(1H)-one was confirmed by X-ray analysis.
