Synthesis of Co(II) complex with ligand of Salen type bearing "free" carboxy-groups and its catalytic activity in asymmetric oxidation of methylphenylsulfide
Анотація
Recently, the metal complexes with ligands of Salen type have been actively studied as catalysts for various organic reactions. Selective sulfoxidation of sulfides to chiral sulfoxides is one of the important ways to obtain useful compounds that have been widely used in organic synthesis and medical chemistry. Some metal-salen complexes of Mn(III) and Ti(IV) showed catalytic activity in selective sulfoxidation of sulfides, but this processes were carried out in environmentally non-friendly solvents, such as chlorinated ones. There were multiple attempts to replace organic solvents by water.
