And the article was published in Research on Chemical Intermediates in 2019. Electric Literature of C8H8O2 The author mentioned the following in the article:
Ni0 nanoparticles were immobilized on acid-activated montmorillonite (Ni0-Mont) by anchoring Ni(OAc)2·4H2O on modified micro/mesoporous montmorillonite followed by reduction with ethylene glycol. The prepared clay composite system was then characterized using Fourier-transform IR (FT-IR) spectroscopy, SEM, energy-dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD) anal., and Brunauer-Emmett-Teller (BET) anal. SEM anal. revealed perfect dispersion of metallic nickel nanoparticles with size distribution of 6-41 nm on the clay matrix. Micro/mesoporous montmorillonite was prepared by activation of Na+-montmorillonite with HCl (4 M) under controlled conditions. The catalytic activity of the prepared Ni0-Mont clay was studied in one-pot microwave-assisted synthesis of biscoumarins and bisdimedones via Knoevenagel reaction of aromatic aldehydes with 4-hydroxycoumarin or dimedone in solvent-free conditions. All reactions were carried out at room temperature within 5-15 min (for biscoumarins) and 5-20 min (for bisdimedones) to afford the products in high to excellent yield. The reusability of the Ni0-Mont catalyst was also investigated in seven consecutive cycles, without significant loss of catalytic activity. In the experimental materials used by the author, we found 2-Methoxybenzaldehyde(cas: 135-02-4Electric Literature of C8H8O2)
2-Methoxybenzaldehyde(cas: 135-02-4) is found in cassia oil, cinnamon bark, and cinnamon bark oil. It is a clear colorless liquid with a strong aroma. It has been used to examine the acaricidal activity of Periploca sepium oil and its active component against Tyrophagus putrescentiae.Electric Literature of C8H8O2
