With the goal of preparing Ti(IV) complexes bearing a
sulfur-based
redox function of possible use in electrocatalytic oxidations of alcohols
at electrode surfaces, a series of seven 2,2′-dithiodianiline
Schiff-base derivatives, including two new variations, were tested
in reactions with Ti(OR)4 (R = iPr, tBu). Instead of the expected dimetallic products of general formula
[LTi(OR)2]2, mononuclear species LTi(OR)2 were obtained, confirmed by crystallographic determinations
to have an unprecedented, symmetrical, and macrocyclic arrangement
with four-point binding to the metal center and with the disulfide
moieties remaining uncoordinated. Cyclic voltammetry performed in
CH2Cl2 displayed oxidations at potentials useful
for fuel cells (+1.1–1.5 V vs Ag/AgCl), but despite the uncoordinated
disulfide moieties, the complexes were reticent to engage in reduction
processes.
