The
bis-sulfoxide ligand <i>p</i>-tolyl-binaso and its derivatives
can be used to synthesize neutral and cationic palladium and platinum
complexes. Various Pt bis-sulfoxide complexes could be made by using
the precursor Pt{(<i>M</i>,<i>S</i><sub><i>S</i></sub>,<i>S</i><sub><i>S</i></sub>)-<i>p</i>-tolyl-binaso}Cl<sub>2</sub> (<b>5a</b>) and abstracting
the chlorides with silver salts. The Pd analogue of this compound
(<b>4</b>) could not be used in the same way. In this case,
the sulfoxides appear to be very weakly coordinated and different
methods to make stable Pd bis-sulfoxide complexes had to be found.
The nature of the bonding in the synthesized compounds was studied
through analysis of their IR and NMR spectra and X-ray crystal structures.
These studies revealed that the <i>trans</i> effect of other
ligands in the complex is quite significant in determining the lability
of the metal–sulfoxide bond. Some of the more stable platinum
structures were then tested for their activity as catalysts in hydroboration
and diboration reactions.
