| dc.description.abstract | The chemical, physicochemical, theoretical and metal
coordination studies of phospholes which have so far appeared
in the literature are reviewed briefly with particular reference
to the electronic structure of the system.
The coordinating properties of the simple phospholes
1-phenylphosphole (PP), 3-methyl-1-phenylphosphole (mPP), 3,4-
dimethyl-l-phenylphosphole (dPP) and 3,4-dimethyl-1-rwbutylphosphole
(dBP) with the metal ions Re(III), Ru(III), Ru(II), Co{II),
Rh(III), Ir(III), Ni(II), Pd(II), Pt(II), Cu(I) and Hg(II) and
also with carbonyl complexes of Ru(II) and Rh(I) have been studied. ...
Differences in the behavior of the various phospholes
studied here, and also other phospholes, in complex formation are attributed to variations in the substitution pattern with the
type of substitution at the phosphorus atom being apparently of
particular importance.
The results are discussed in terms of orbital perturbation
of a pyramidal phosphole in which the HOMO may not be the
lone-pair orbital and also in terms of a pyramidal but aromatic
phosphole system. | |
