There is a
long-standing interest in the electrochemistry of phosphines with ferrocene
backbones. We have chosen to investigate
the structure and electrochemistry of two classes of ferrocenylphosphines. The first class includes compounds with
methylene spacer groups between the phosphorus and ferrocene backbone. The previously synthesized compounds [FcCH2)4P+][I-],
[(FcCH2)3PH+][BF4-], and
(FcCH2)P were examined. The
oxidative electrochemistry is complicated and strongly depends on the
supporting electrolyte used.

The second class
consists of 1,1'-bis(diaminophosphino)ferrocene (dapf) derivatives. Two types of compounds containing dapf were
synthesized and examined. In the first
type, the dapf serves as a bidentate ligand in [MCl2(dapf)] (where M
= Pd or Pt). The second type consists of
phosphine chalcogenides of the form dapfE2 (where E = Se or S). Electrochemistry of the Pt, Pd, and S
compounds was straightforward, whereas the electrochemistry of the Se compound
was complicated. X-ray crystallographic
studies of the S and Se compounds have been performed.
