The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article£¬once mentioned of 14187-32-7, Formula: C20H24O6
Modified Crown Ether Catalysts. 2. Synthesis of Alkanoyl-, Aroyl-, alpha-Hydroxyalkyl- and Alkylbenzo and Alkylcyclohexano Crown Ethers
Improved procedures for the synthesis and purification of alkanoyl- and aroylbenzo crown ethers are reported.Several new alkanoyl- and alpha-hydroxyalkylbenzo crown ethers were prepared.Alkylbenzo crown ethers were prepared in high yield by the Raney nickel catalyzed hydrogen-transfer reductions of the corresponding acyl- or hydroxyalkylbenzo crown ether compounds.The reduction of the tosylhydrazones of acylbenzo crown ethers with sodium borohydride in acetic acid also yielded the corresponding alkyl derivate.Attempted reduction of the acyl- and alpha-hydroxyalkylbenzo crown ethers by catalytic hydrogenation over palladium catalysts was unsuccessful apparently due to strong binding of the crown ethers to the catalyst.Alkylcyclohexano crown ethers were prepared by catalytic hydrogenation of the aromatic rings of the corresponding alkylbenzo crown ethers.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 14187-32-7 is helpful to your research., Formula: C20H24O6
