Two New Organic–Inorganic Hybrids Based on [SiW12O40]4− Anion: Hydrothermal Syntheses, Crystal Structures, and Electrochemical Properties

[C6(MIm)2]2W10O32. 2H2O: A novel and powerful catalyst for the synthesis of 4-arylidene-2-phenyl-5(4)-oxazolones under ultrasonic condition

“…Thin layer chromatography (TLC) was performed on UVactive aluminum-backed plates of silica gel (TLC Silica gel 60 F254). 1 H, and 13 C NMR spectra were measured on a Bruker DPX 400 MHz spectrometer in DMSO-d 6 with chemical shift (d) given in ppm relative to TMS as internal standard. Coupling constants are given in Hz.…”

“…The development of hybrid organic-inorganic frameworks due to replacing toxic metal catalysts with degradable organic compounds has emerged as one of the most potentially significant fields of investigation in modern chemistry [1]. Recently, hybrids of ionic liquids with polyoxometalates (POMs) have grown tremendously, not just as novel inorganic materials [2][3][4], but also as green catalysts and anti-tumor agents [5], have been increasingly known.…”
