Abstract
The graphite felt electrode, coated with ca. 3 wt% polyacrylic acid, was modified by successive reactions with hexamethylenediamine (for cross-linking), 4-amino-2,2,6,6-tetramethylpiperydinyl-1-oxyl(4-amino-TEMPO) and diazomethane (for methylation). Properties of the electrode, were compared with a non-crosslinked and non-methylated one, a crosslinked and a non-methylated one, and a crosslinked and incompletely methylated one; the present electrode was stable and oxidized nerol to neral selectively with turnover number > 1560.Keywords
