The solutions with the problems regarding the ligand effects in homogeneous catalysis through December 2007 has been given. Specifically, the problems with the obvious differences in reactivity and selectivity that comes from changing neutral or anionic ligands will be addressed with a focus on ligands and complexes that enables enantioselective catalysis. There are at times when catalyst choice gives off better improvement within the reaction yields or efficiencies. Meanwhile, an emphasis will be given on the privileged ligands and catalysts for a given class of reactions. Finally, the Hayashi/Ito asymmetric aldol reaction will be dealt with.
