Abstract
The present work describes the excellent catalytic activity of copper(II) oxide nanoparticles (NPs) towards N-arylation of aniline and imidazole at room temperature. The copper(II)oxide NPs were synthesized by a thermal refluxing technique and characterized by FT-IR spectroscopy; powder XRD, SEM, EDX, TEM, TGA, XPS, BET surface area analysis, and particle size analysis. The size of the NPs was found to be around 12 nm having a surface area of 164.180 m2 g–1.The catalytic system was also found to be recyclable and could be reused in subsequent catalytic runs without a significant loss of activity.

Modified Procedure for Preparing CuO NPs Copper(II) chloride dihydrate (6.8 g), NaOH (3.2 g), and capping solvent (polyethylene glycol) were mixed in a 2:1:1.5 ratio with EtOH–H2O (1:1, v/v, 200 mL) in a round-bottom flask fitted with a reflux condenser. The mixture was heated to reflux for 12 h and allowed to cool to r.t. Then the mixture was again heated to reflux for 5 h. The dark brown precipitate was centrifuged and washed with EtOH, acetone, and hot H2O sequentially. Finally, the product was dried at r.t, heated to 120 °C in a vacuum oven and allowed to cool to r.t.

- 19 Typical Procedure: N-Arylation of Aniline with Phenylboronic Acid In a 50 mL round-bottomed flask, aniline (0.5 mmol), phenylboronic acid (1 mmol), K2CO3 (1.5 mmol), nanocatalyst (30 mol% with respect to aniline substrate) were added and stirred in MeOH–H2O (1:1) under air at r.t. for the required time, monitoring by TLC. After completion, the mixture was diluted with H2O, and the product was extracted with EtOAc (3×). The combined extracts were washed with brine (3×) and dried over Na2SO4. The product was purified by column chromatography (60–120 mesh silica gel, eluting with EtOAc–hexane solvent). The product was a grey crystalline solid, mp 54 °C; isolated yield: 92%. 1H NMR (400 MHz, CDCl3): δ = 5.63 (br s, 1 H), 6.90 (t, J = 8 Hz, 2 H), 7.04–7.02 (m, 4 H), 7.25–7.21 (m, 4 H) ppm. 13C NMR (100 MHz, CDCl3): δ = 143.2, 129.5, 121.1, 117.9 ppm.
