They have received a Chinese invention patent for the technique. The patent is No. ZL：200810189023.6 received on April 27, 2011.
Complicated and expensive organic ligands are normally essential in fine chemical synthesis at preparative or industrial levels. The synthesis of fine chemicals by using heterogeneous catalyst systems without additive organic ligand is highly desirable but severely limited due to their poor generality and rigorous reaction conditions.
