Optically active co-ordination compounds. Part XXII. Stereoselectivity in isomers of the (L-glutamate)bisethylenediaminecobalt(III) ion

Abstract

The formation and properties of the D- and L-diastereoisomer of formula [Co(en)₂(L-glut]⁺(L-glutH₂ is L-glutamic acid), where L-glut is chelated to cobalt as an α-amino-acidate, have been studied. It is shown that of the many possible diastereoisomers only four are formed, and that the stereoselectivity is kinetic in origin.
