Bidentate chiral phosphine ligands have received increasing
attention because of their important role in the development
of asymmetric catalytic applications of transition metal complexes.
1 The substituents at the two phosphorus atoms play an
important role in the steric and electronic properties of the
ligands.2 Their nature determines the relative donor/acceptor
ability of the phosphines.3 Dicarba-closo-dodecaborane(12) is
a particularly interesting substituent or backbone because
of its electron-withdrawing character,electron-delocalizing
ability,and large size.4
Derivatives of bidentate bis-phosphinodicarba-closododecaboranes(
12) can form stable complexes with platinum(
II) and palladium(II) because of their ability to form
five-membered chelate rings.5 Lately,severalmetal complexes
with five-membered chelate rings were reported to exhibit
high catalytic activity.6
