and the product 3 is an active acyl compound, which is more sensitive to 6-fluoro-2-pyridylmagnesium chloride, therefore The effect of reaction temperature on the yield of 3 was also examined. Increasing the temperature will reduce the yield of 3. For example...
The acid halide or acyl halide functional group comes from a carboxylic acid where the OH is replaced by a halogen or halide. You’ll recognize the acid halide as a terminal group with a carbonyl bound to a halogen. Acid halides are very unstable and highly reactive as you’ll see in yo...
It has excellent mechanical properties and is able to perform in high temperature applications. Polyimide is a polymer constructed from an imide monomer, which has two acyl groups bonded to nitrogen. The mechanical and thermal properties of polyimide have increased its use with electromagnetic coils ...
But things didn’t go as planned. ‘When Christian did that reaction, he got a by-product, he never could get his acyl chloride to couple,’ Meldal recalls. ‘He came down to me and was initially really devastated because his project didn’t work.’ But instead of throwing it out, th...
Poprezinc is a new anti-ulcer drug developed by Japan's Hamari New Drug Co., Ltd. It is the first zinc-containing compound for clinical use. The drug was launched in Japan in 1994 under the trade name Promac in the form of granules. agent. Polaprezinc is a Polaprezinc complex. L-...
The present research provides data on the density (ρ), viscosity (η) and ability to absorb carbon dioxide of systems containing amine, molecular solvent (MS) and choline chloride (ChCl), with the investigation of the physical properties of both neat amine/MS/ChCl mixtures and their samples...
