- W612079356 abstract "This thesis describes the development and applications of new chiral bis(isonitrile) ligands in catalysis. These ligands are capable of forming very stable complexes with various transition metals such as Pd, Fe, Cu, Rh and Ir. Synthesis of the requisite bis(isonitrile) ligands was achieved in moderate yields via lithiation of 2-oxazolines and subsequent treatment with phenylphosphonic dichloride at low temperature.Palladium-bis(isonitrile) complexes were found to catalyze the Wacker oxidation of aliphatic and styrenes in the absence of further cocatalysts gives rise to methyl ketones in a highly chemoselective manner. A new type of iron-bis(isonitrile) catalyst was also developed, effective in asymmetric transfer hydrogenations of aromatic and heteroaromatic ketones. The noteworthy feature of the iron complexes employed in our study are coordinating isonitrile groups that might serve as acceptors for hydrogen that is subsequently delivered to the ketone being activated by the iron centre. In addition, this is the first report that demonstrates the ability of isonitriles to be able to serve as chiral ligands in asymmetric catalyses." @default.
