Effective ligands for asymmetric reactions catalyzed by transition metals, including hydrogenation and dimethylsilylation. 2,2 '-bis (diphenylphosphine)-1,1' -binaphthalene and its rhodium and ruthenium derivatives can be used as highly selective homogeneous catalysts for the reduction reactions of aryl ketones, β-ketonates and α-amino ketones. It can also be used for asymmetric hydrogenation Chemicalbook and hydroformylation of olefins, asymmetric Heck reaction and asymmetric isomerization of allyl. The Ag(I) complex can be used to catalyze the asymmetric aldol reaction between aldehydes and aldehydes. The Ag(I) complex can also be used to catalyze asymmetric heterogeneous Diels-Alder reactions of azo compounds.
