Determination of the maximum retention of cobalt by ion

Before cobalt ion exchange, the zeolites ZSM5 and Mordenite were converted to their protonic form. Hence, NaZSM5 was pretreated by contacting the powdered material with an aqueous solution of 2 mol/L NH 4 Cl (NH 4 + /Al 3+ = 7) at 70ºC/1 h, under stirring. During the filtration process, the zeolite was submitted to a new exchange procedure by the addition of ammonium solution on the

Isolable chiral rhodium(I) complexes bearing a helical arylsubstituted 1,3,5hexatriene chain were synthesized by onepot reactions of [Rh(nbd)Cl] 2 with aryl boronic acids and diphenylacetylenes in the presence of 50 % aqueous KOH (see scheme). The persistent helical chirality of the complexes enabled their separation into enantiomers by HPLC on a chiral stationary phase.
