1,1 -Binaphthalene-2,2 -diamine derivatives

An MlP-catalyzed ene reaction between a diketone and an alkene was used to further investigate this phenomenon. The most easily accessible binding sites of an MIP-containing chiral phosphine platinum complexes were poisoned by using diamine derivatives of binaphthol (i.e., 2,2 -diamino-l,l -binaphthalene BINAM) to block access to the substrate (Scheme 20)." ... 

Sulfur transfer. The reaction with arenediazonium salts leads to diaryl disulfides. Interestingly, l,l -binaphthalene-2,2 -dithiol is the only product (61% yield) in the reaction with the bis-diazonium salt derived from l,r-binaphthyl-2,2 -diamine.
