资源简介：
The complexes TpW(NO)(PMe3)(L), where L =
phenol, N,N-dimethylanilinium, or naphthalene, undergo
protonation followed by addition of an aromatic nucleophile. The addition
of aromatic molecules occurs at the para carbon of the phenol or aniline
ring or the beta carbon of the naphthalene. The addition occurs anti
to the metal fragment, as determined by X-ray crystallography. In
the case where L = phenol or N,N-dimethylanilinium,
treatment of the bound arene with an electrophilic heteroatom followed
by an aromatic nucleophile sets two stereocenters, with both additions
occurring anti to the metal. The resultant ligands have been removed
from the metal by oxidative decomplexation using ceric ammonium nitrate.
