A series of chiral lipophilic Cu(Ⅱ) complexes were investigated as catalysts for the enantioselective hydrolysis of R(S)-p-nitrophenyl N-dodecanoyl-phenylalaninate in micelles. The highest enantioselectivity (kR/ks=7...A series of chiral lipophilic Cu(Ⅱ) complexes were investigated as catalysts for the enantioselective hydrolysis of R(S)-p-nitrophenyl N-dodecanoyl-phenylalaninate in micelles. The highest enantioselectivity (kR/ks=7. 81) was observed in a mixed micellar system composed of 1-Cu(Ⅱ) and Brij35.展开更多
Manganese (III) porphyrins bound to chloromethylated polystyrene bearing some polyglycol chains are efficient catalysts for the epoxidation of styrene by sodium hypochlorite.
Lipophilic complexes of macrocyclic 12-membered dioxotetraamine ligand bearing bis-hydroxy groups as functional pendants are effective catalysts for the hydrolysis of amino acid esters in micellar media, and the rate ...Lipophilic complexes of macrocyclic 12-membered dioxotetraamine ligand bearing bis-hydroxy groups as functional pendants are effective catalysts for the hydrolysis of amino acid esters in micellar media, and the rate enhancement of more than 10-fold were observed.展开更多
