Abstract: Oxidation of CoSO₄ in the presence of s -leucine using РbО₂ as oxidizing agent in the presence of activated charcoal leads to the synthesis of trans-  -Λ,Δ-Co(s-leuciriate)₃ and only a small amount of Λ,Δ-cis isomer. Without catalysis a mixture of trans-Λ,Δ and Λ-cis isomers were obtained. Reaction yields are discussed in terms of different isomer stabilities. Thermal gravimetric analysis of trans isomers showed, that dehydratation occurs at 40— 160°C.
