Diphenylphosphino -V,-dimethyl-1,1-binaphthalen-2-amine

Physical Data (/ )-(—) amorphous solid, [a]o —19.0 (c 1.0, THF). (S)-(+) amorphous solid +26.6 (c 1.0, THF). Solubility (/ )-(+) and (5)-(—) very well soluble in toluene, CH2CI2, AcOEt, THF well-soluble in ether sparingly soluble in MeOH, EtOH, and hexane. 

Drying standard drying during the work up not hygroscopic. 

Handling, Storage, and Precautions keep tightly closed, store in a cool dark place deteriorates when exposed to direct sunshine and air. 

In allylic substitution and presumably in other reactions (vide supra), MAP acts as an RCjpso-ligand rather than PN-ligand, as evidenced by NMR and X-ray crystallography (eq 6). Strong memory effects, observed in the case of allylic substitution of cyclic substrates, are associated with this unusual coordination.
