Discontinued product2-Methyl-3-oxo-pentanoicacid methyl ester
CAS:The synthesis of 2-methyl-3-oxo-pentanoic acid methyl ester is accomplished by a three step process. The first step is the intramolecular condensation of 2,2-dimethylpropionic acid with acetone to form a 1:1 mixture of 3,4-dihydroxybutyl and 4,4-dihydroxybutyl esters. The second step is the selective transesterification of the 3,4-dihydroxybutyl ester with benzaldehyde. This reaction provides an optically pure 2-methyl-3-oxo-pentanoic acid methyl ester as the major product. The third step is an aldol condensation between the ketone from the second step and acetone to produce another optically pure 2,2 dimethylpropionic acid methyl ester.Formula:C7H12O3Purity:Min. 95%Molecular weight:144.17 g/mol(2-Chloroethoxy)(2-chloroethyl)phosphinic acid

CAS:Controlled Product2-Bromo-3,3,3-trifluoro-1-propene is a chemical compound that has been synthesized in an asymmetric reaction. The reactant is bromopropane and the product is 2,2,2-trifluoropropene. The methylene group on the propene molecule is activated by the nucleophilic attack of a fluoride ion from hydrogen fluoride to form a cavity with a highly strained bond. The kinetic study of this reaction revealed that the activation energy for the reaction is 42 kJ/mol. Palladium-catalyzed coupling reactions are catalyzed by palladium and require nonpolar solvents such as toluene or dichloromethane. This type of reaction has been shown to be exothermic with an isolated yield of 1%.
