36216-80-5, A heterogeneous catalyst is a catalyst that is present in a different phase than the reactants. Such catalysts generally function by furnishing an active surface upon which a reaction can occur. 36216-80-5, name is Benzo[d]isoxazol-3-amine, introduce a new downstream synthesis route as follows.
To a solution of triethylamine (0. 0025 mol) in CH2Cl2 (5 ml) benzoylchloride (0.0025 mol) was added. The mixture stirred at RT and intermediate 3 (0.0025 mol) in CH2C12 (5 ml) added dropwise. The reaction mixture was stirred overnight at RT. The mixture was washed 2 times with H20. The organic layer was separated, dried (MgS04), filtered off and the solvent was evaporated. The residue was purified by column chromatography over silicagel (eluent CH2Cl2) yielding O. OlOg compound 9 (yield of 2%, Melting Point 133C) and a fraction which was further purified by column chromatography over silicagel (eluent hexane/CH2Cl2) yielding 0.225 g of compound 10 (yield of 38%, Melting Point 97C-100C), and 0.100 g of compound 11 (yield of 17%, Melting Point 154C-160C)., 36216-80-5
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about Benzo[d]isoxazol-3-amine.
