The macrocyclic tetraene 2,3,9,10-Me4[14]tetraene (tmt) may be synthesized by a metal-directed condensation between trimethylenediamine (tn) and 2,3-butanedione in the presence of Co(OAc)2, ultimately resulting in the trans-dichloro Co111 complex [Co(tmt)Cl2]+ (59).302...

Five- and six-membered rings formed by coordination of diamines with a metal ion have the stereochemical characteristics of cyclopentane and cyclohexane. The ethylenediamine complexes have puckered rings and the trimethylenediamine complexes have chair conformations. The methylene protons are nonequivalent in these nonplanar conformations, taking on the character of equatorial and axial substituents. They are made equivalent as the result of rapid conformational inversion at room temperature, just as in the alicyclic compounds (Fig. 7.1). This has been observed in nmr studies of planar and octahedral complexes of ethylenediamine-type ligands with a number of metals. 

In the condensed chelate systems, many kinds of chelating agents were used, such as ethylenediamiiie-/V,/V,/V, /V -tetraacetic acid (EDTA), nitrilotriacetic acid (NTA), /-aspartic acid (AA), trimethylenediamine (TMD), /V,/V-dimethylethylenedi-amine (DMED), diethylenetriamine (DETA), triethylenetetraamine (TETA), and t ris(2-aminoethyl)amine (TAEA) (6). The chelating agents used are listed in Table 3.2.1. 

It is insoluble in water, microcrystallinc, and lilac in colour.1 Many of these derivatives of platinum containing organic bases have been obtained in optically active forms. Those containing 1-propylene-diamine will serve as examples. These are easily prepared, and as they are remarkably stable are easily examined for optical properties. The compounds are prepared by the interaction of cis-dichloro-l-propylenc-diamino-platinum, [Pt pnCl2], with the calculated quantity of the corresponding base, 1-propylcnediamine, ammonia, ethylenediamine, or trimethylenediamine. The liquid obtained is evaporated on a water-bath and precipitated with alcohol. The di-derivative of 1-propylene-diamine, [Pt pns]Cla, has rotation [a]o+46-37°, [M]r>+192-0°.

Since many ligands are organic compounds which have possibilities for isomerism, the resulting complexes can show isomerism from this source. Examples of isomeric ligands are 1,2-diaminopropane ( propylenediamine, pn) and 1,3-diaminopropane C trimethylenediamine, tn) or ortho-, meta-, and pcra-toluidine fCH3C6H4NH2).

In recent work we have shown that interaction of tn2Co (aq) with pyrophosphate (1) and with ATP (2) in aqueous solution can lead to large rate enhancements (up to 10 -fold in neutral media) for hydrolysis within a P-O-P linkage [tn = trimethylenediamine ...

The precipitates obtained so far by our Japanese research group are summarized in Table I. (The abbreviations used are as follows en, ethylenediamine tn, trimethylenediamine. ) From these results, the following systems are considered to be applicable for the recovery and separation of actinides. 

Hexamminecobalt(III) salt cannot be used as a precipitant in the oxalato complex precipitation system because it precipitates as hexamminecobalt(III) oxalate. Besides the hexaureachro-mium(III) salt, hexamminechromium(III), tris(ethylenediamine)cobalt (III) or tris(trimethylenediamine)cobalt(III) salts can be used as precipitants. Hexamminechromium(III) and tris(ethylenediamine) cobalt (III) salts form precipitates with actinide(IV) or (VI) oxalato complex ions, whereas tris(trimethylenediamine)co-balt(III) salt forms precipitates with Th(IV) or U(VI) oxalato complex ions leaving Pu(IV) ion in the supernatant solution.Therefore, this reagent plays the role of both a separating agent and a precipitant and is applicable for the separation of Pu(IV) ion from Th(IV) or U(VI) ion.
