A nanometric carbon CMK-3 modified with octylimidazolium ionic liquid (OctIm) and MoO42- as a new hybrid catalyst was synthesized. The study is the first to report a successful immobilization of MoO42- on the CMK-3/OctIm as a hybrid nanocatalyst. A variety of anal. methods were utilized to determine the properties of the structure and morphol. of the synthesized nanocatalyst [CMK-3/OctIm/ MoO42-]. The anal. techniques were transmission electron microscopy (TEM), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), inductively coupled plasma (ICP), X-ray diffraction (XRD), N2 isotherms (BET), IR spectroscopy and thermogravimetric anal. (TGA). CMK-3/OctIm/ MoO42- hybrid catalyst demonstrated a considerable catalytic activity. It is a recyclable nanocatalyst that is utilized to chemoselectively oxidize different types of sulfides RSR1 (R = Me, Ph, prop-2-en-1-yl, etc.; R1 = Me, Ph, cyanomethyl, etc.) and thianthrene to the corresponding sulfoxides RS(O)R1 and thianthrene,5,10-dioxide and benzylic alcs. R2CH2OH (R2 = Ph, 3,4,5-trimethoxyphenyl, 3-chlorophenyl, etc.) to aldehydes R2CHO using the green oxidant, hydrogen peroxide (H2O2) in high-yields. With a little leaching and variation in activity, it is possible to recover and reuse the catalyst frequently. A combination of molybdate anion and the CMK-3 order mesoporous carbon resulted in an improvement in the performance of catalysis and ease of separation for the reaction procedure. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Computed Properties of C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Computed Properties of C11H20N2
