title: Selection of two optional covalent bonds by electric stimuli: dual catalytic switching of redox-active copper.
abstract: Two types of redox functionality were selected for covalent immobilization on a carbon electrode, using an electric potential as the sole stimulus. A redox-active copper catalyst transformed a terminal alkyne in two ways with and without an oxidation process, to form a triazole or butadiyne.
