nol ligands that introduces the ortho-substituent in the
next to last step. This approach provides a highly
convergent route to many ligand structures in addition
to the ones reported herein. The coordination chemistry
of these ligands parallels that of the unlinked cases in
many ways, though octahedral coordination environ-
ments bring out their differences.

[10] The 4-vinyl analog of 5 was obtained by a different route since the
vinyl group is hydrohalogenated under the conditions of Scheme
2. It is obtained in pure form by treating the ligand first with
Ti(NEt2)2(OiPr)2, and then SiCl4, see footnote 13.
