COPPER(I) COMPLEXES WITH POLYMERIC BIQUINOLINE-CONTAINING LIGANDS
65
hydride, and a fraction with bp 41°C was collected.
The PA polymer was synthesized according to the
procedure reported in [17]. Steroids I and II were
synthesized by standard methods [18, 19]; the other
examined alcohols were commercially available prod-
ucts (from Aldrich).
This study was performed under financial support
by the Russian Foundation for Basic Research (project
nos. 08-03-00142, 07-03-00619, 07-03-90824).

Mass-spectrometric analysis of reaction mixtures
was performed on a GC–MS system including
a Hewlett–Packard 5973 mass selective detector (HP-
5MS column; detector and injector temperature 280°C;
oven temperature programming from 70 to 320°C at
a rate of 15 deg/min). The NMR spectra were measured
on a Bruker Avance 400 spectrometer. Electrochemical
oxidation was performed in a 100-ml diaphragmless
cell using a P-5827 M potentiostat. Graphite fabric
with a specific surface area of 12 m2/g, 5×25 mm,
containing preliminarily immobilized [CuI(PA)L2]·
ClO4 complex [14] was used as working electrode, and
a platinum electrode was used as auxiliary one. In all
cases, a saturated silver chloride electrode was used as
reference (redox potential –0.43 V in acetonitrile
relative to Fc/Fc+).

Electrocatalytic oxidation of alcohols with at-
mospheric oxygen in the presence of [CuI(PA)L2]·
ClO4 immobilized on the surface of a graphite
electrode. Alcohol I, 0.125 mmol, was dissolved in
50 ml of acetonitrile containing 0.05 mol/l of Bu4NBF4
or in methylene chloride containing 0.15 mol/l of
LiClO4, and preparative electrolysis was performed in
the potentiostatic mode at a working electrode poten-
tial of –0.55 V relative to Ag/AgCl/KCl. During the
electrolysis process, a 1:1 mixture of argon with air
was passed through the solution at a flow rate of
24 ml/min. The reaction was terminated when 2 F/mol
of electricity (calculated on the initial alcohol) was
passed. The reaction mixture was analyzed by GC–MS
in the presence of mesitylene as standard, as well as by
1H and 13C NMR spectroscopy.
