The First Examples of Enantiomerically Pure Diphosphane Dioxides-(RP,RP)- and (SP,SP)-1,2-Di-ter-butyl-1,2-diphenyldiphosphane 1,2-Dioxides, and (RP)- and (SP)-1-tert-Butyl-1,2,2-triphenyldiphosphane 1,2-Dioxides

Whereas oxidative dimerization of each of the lithiated reagents (RP)‐ and (SP)‐tert‐butylphenylphosphane oxides 1 Li and 2 Li by means of oxygen in THF at low temperature led cleanly to meso‐1,2‐di‐tert‐butyl‐1,2‐diphenyldiphosphane dioxide (3), the respective nucleophilic substitution reactions of...
