The efficient functionalization of planar chiral ruthenium naphthaleneand ruthenium indenylscaffolds is reported. Mild reaction conditions employing microwave heating have been developed for the derivatization of sensitive cationic naphthalene ruthenium complexes. In particular, a series of novel planar chiral monodentate phosphines and their gold­(I) complexes have been synthesized and fully characterized by NMR spectroscopy and X-ray crystallography. Furthermore, the electronic properties of these phosphines (L) have been evaluated via the infrared CO stretching frequencies of the corresponding Ni­(CO)3(L) complexes, providing valuable insight for the design and application of these chiral ligands in asymmetric catalysis.
