naphthaleneand
ruthenium indenylscaffolds 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.
