Stereochemistry of complex inorganic compounds. 37. Stereoselective effects in reactions of cobalt complexes containing d- and l-phenylethylenediamine
The stereoselectivity of complex ions that depends upon the chiral nature of the ligands has been studied extensively with the hope of using it in the optical resolution of chiral ligands. Earlier studies have centered upon 1,2-propanediamine (pn) and stilbenediamine (stien). This paper is concerned with complexes containing phenylethylenediamine (phenen). The complexes of [Co(d-phenen)2(d-tart)]+ and [Co(d-phenen)2(l-tart)]+ react with Pb2+ and Ba2+ at quite different rates. This offers a method of separating the tartrate isomers.
