Salicylidene ethylenediimine

Materials anhydrous TBHP was made by extracting a 70% TBHP solution (in water) in chlorobenzene and drying over 3A molecular sieves, to result in a 5 M solution. Cyclohexene and cyclooctene were distilled and were passed through a column of basic alumina before use. Vanadyl(IV) sulphate hydrate, Salen (N,N -bis(salicylidene)-ethylenediimine), 1,2,-dichloro-ethane (DCE), dichloromethane (DCM), acetone, and acetonitrile were reagent grade and used as received. (-) Carveol was purchased as a 1.48 1 mixture of trans- and cis-carveol and used as such. Cumylhydroperoxide was purchased as a 80% solution in cumene and used as received. 

Distribution ratios (chloroform-water) have also been reported for curium complexes with 8-hydroxyquinoline (oxineX cupferron, and JV-benzoyl-phenylhydroxylamine (NBPHA) [136]. Only 1 3 complexes with Cm(iii) and Am(iii) were reported, and extraction into the organic phase appears to be very high at pH values above 5. Solution interaction of Cm(iii) with bis(salicylidene)ethylenediimine (SALEN) and derivatives has also been studied [137], With the reagent arsenazo(iii), both Cm(iii) and Am(iii) form 1 1 and 1 2 complexes [138].
