Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 14098-44-3, Name is Benzo-15-crown-5, Product Details of 14098-44-3.
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.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Product Details of 14098-44-3. In my other articles, you can also check out more blogs about 14098-44-3
