1,1'-Binaphthyl-2,2'-diamine Chemical Properties,Usage,Production
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.
