| Benzyl thioether complexes of Co(III) undergo decomposition in basic solution by several pathways with only a small amount of the product formed being that expected by the route of Co-S cleavage. Base hydrolysis of cobalt(IIII) complexes coordinated by phenyl thioether ligands (see figure) is of interest for two reasons: will removal of the benzylic hydrogens lead to clean Co-S cleavage, and, if so, do different subsituents on the phenyl group lead to different rates of base hydrolysis? Preparation of three phenyl thioethers ligands (X = H, Br, Me) are described. Three synthetic routes for synthesis of the desired product are evaluated. Initial experiments suggest that the new complexes undergo base hydrolysis cleanly by Co-S cleavage.
