Reduction of pyruvate by titanium(III)

Autor: E. Vrachnou-Astra, D. Katakis, J. Konstantatos

Publikováno v: Inorganica Chimica Acta. 85:41-47

Titanium(III) in aqueous solutions reacts with carbonate-like pyruvic acid and/or pyruvate to give a product of reductive coupling. The reaction was investigated kinetically over a range of hydrogen ion concentrations from 0.007 M to 2.5 M and over a

A mechanistic study of the reduction of cystine by vanadium(II) in the pH range from 7.5 to 12

Autor: J. Konstantatos, E. Vrachnou, D. Katakis, G. Kalatzis

Publikováno v: Inorganica Chimica Acta. 151:191-195

The reduction of cystine by aqueous vanadium(II) was investigated in the p..H range from 7.5 to 12. The product ratio [VIV] /[VIII] reaches a maximum at pH ca. 9 and depends linearly on the excess concentration of cystine. It is also affected by cyst
