(a) general reaction mechanism for AS101 and its analogue in presence of water (X stands for halide ligands) and (b) computed reaction profiles for the hydrolysis of AS101 and its bromide and iodide derivatives. Gibbs free energy (GFE) values in kcal/mol are displayed. R, RA, TS, PA, Int, and P stand for reactant, reactant-adduct, transition state, product-adduct, intermediate, and product, respectively. Color scheme for the 3D structures above: Te (violet), Cl/Br/I (green), O (red), C (grey), and H (white).
