A short synthesis of (±)-cherylline dimethyl ether
A synthesis of ±-cherylline dimethyl ether is reported. The key steps involved are Michael-type addition, radical azidonation of an aldehyde, Curtius rearrangement, and reduction of an isocyanate intermediate followed by Pictet-Spengler cyclization.
متن کاملVibrational spectrum of magnesium hydride
The vibrational spectrum of hydrogen atoms in magnesium hydride has been studied by means of inelasticneutron and Raman-scattering experiments between 12 and 295 K. After careful evaluation of multiple scattering and multiphonon contributions, we provide a vibrational frequency spectrum up to 180 meV and the mean-square displacement of hydrogen atoms. The inelastic light scattering spectra of M...
متن کاملEffects of Buffer Gas Composition on Autoignition of Dimethyl Ether
Experimental and numerical studies are conducted on the thermal, chemical and dilution effects of buffer gas composition on autoignition of dimethyl ether (DME). The buffer gases considered are nitrogen (N2), a mixture of N2 and argon (Ar) at a mole ratio of 50%/50% and a mixture of Ar and carbon dioxide (CO2) at a mole ratio of 61.2%/38.8%. Experiments are performed using a rapid compression m...
متن کاملApplication of Novel Gamma Alumina Nano Structure for Preparation of Dimethyl ether from Methanol
In this study, preparation of nano-sized gamma alumina with high specific surface area and high yield by thereaction between aluminum nitrate and sodium carbonate, without using any surfactant is reported. Bohemite (Aluminum oxyhydroxide) was prepared as a precursor by strict control of pH and reaction temperature. The gel produced was purified by washing fol...
