Synthesis of Unsymmetrically Substituted Phosphane Oxides (R super(1)R super(2)P(O)H) and Phosphinous Acids (R super(1)R super(2)POH)

Invited for the cover of this issue is the group of Berthold Hoge at the University of Bielefeld. The image depicts the delicate balance between the unusual form of a phosphinous acid with respect to the corresponding phosphane oxide tautomer by the influence of electron-withdrawing groups.
