trifluoroacetic acid. Computational studies indicated an activation energy of 12.3 kcal mol–1 for hydroxyl interchange at selenium, comparable to the value of 15.5 kcal mol–1 derived from the NMR experiments. The glutathione peroxidase-like activity of 4 was measured in an assay where the catalysis of the reduction of hydrogen peroxide with benzyl thiol was monitored by the appearance of dibenzyl disulfide. The
