Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 550-44-7, Name is 2-Methylisoindoline-1,3-dione, molecular formula is C9H7NO2, belongs to indolines-derivatives compound, is a common compound. In a patnet, author is Mitrofanov, Alexander Yu, once mentioned the new application about 550-44-7, Recommanded Product: 550-44-7.
Selective Metal-Controlled Synthesis of Trifluoromethylated (Indolin-2-ylidene)methyl- and Quinolin-3-ylphosphonates
Metal-catalyzed (Cu, Ag, Au) reactions of alkynylphosphonates with 1-(2-aminophenyl)-2,2,2-trifluoroethan-1-ones were developed. Terminal alkyne diethyl ethynylphosphonate reacted with ketones to give different products depending on the catalyst used. With a CuI/PPh3 catalytic system, the formation of CF3-containing indoline derivatives was observed with good yields. The use of AgSbF6 as a catalyst led to quinoline derivatives in high yields. The less reactive 2-substituted ethynylphosphonates required gold complexes as catalysts to provide the corresponding 2-aryl(alkyl) substituted 4-(trifluoromethyl)quinolin-3-ylphosphonates with good yields.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 550-44-7. The above is the message from the blog manager. Recommanded Product: 550-44-7.
