Calcination Treatment

One-step rapid synthesis of colloidal nano-MnO2 suspension from KMnO4 solution has been readily carried out in the presence of nanocellulose whiskers (NCW) upon a sonochemistry procedure at room temperature. NCW that plays a triple role of a reducing agent and a support, as well as of a stabilizer, has been introduced to obtain stable dispersions of MnO2 nanoparticles. UV-vis spectroscopy, XRD, and TEM were employed to characterize the products. Uniform α-MnO2 nanoparticles of dimensions 20–30 nm were obtained with good crystalinity and phase-purity by air- calcination treatment at 500 °C.

A direct C-H halogenation of 3-aryl-1H-pyrazol-5-amines with NXS (X = Br, I, Cl) as cheap and safe halogenating reagents at room temperature has been developed. This transformation provides an effective metal-free protocol towards the synthesis of novel 4-halogenated pyrazole derivatives with moderate to excellent yields. The method represents simple and mild reaction conditions, broad substrate scope as well as gram-scale synthesis. The utility of this procedure is established by further transformations of the 4-halogenated products. Mechanism studies show that DMSO plays a dual role of catalyst and solvent.
