| (S)-(-)-1,1'-BINAPHTHYL-2,2'-DIAMINE Usage And Synthesis |
| Description | 1,1'-Binaphthalene]-2,2'-diamine is an axially asymmetric binaphthyl ligand mainly used in enantioselective catalysis. | | Chemical Properties | off-white to beige-pink powder | | Uses | Novel axially chiral Rh N-heterocyclic carbene complexes were prepared from axially dissymmetric 1,1'-Binaphthalene]-2,2'-diamine and applied in the Rh-catalyzed enantioselective hydrosilylation of methyl ketones. The enantioselective direct aldol reaction, organocatalyzed by recoverable BINAM- prolinamide derivatives can be highly accelerated by a catalytic amount of a carboxylic acid without a detrimental of the obtained enantioselectivities. | | Safety Profile | Questionable carcinogen withexperimental tumorigenic data. When heated todecomposition it emits toxic fumes of NOx. |
