The same process can be performed the other way round, first performing ammonia oxidation with guest 1, followed by reabsorption with guest 3 and alcohol oxidation as shown in Figure . ). After electrocatalysis (ammonia oxidation with guest 1 on E2, entry E2, Table ) guest 3 is reabsorbed onto the same electrode E2. (c) CV of 2 nd absorption with guest 3 in aqueous NaClO4 (0.2 M, pH 7, 100 mV s -1 ) and (d) CV upon addition of benzyl alcohol (10 mM), to then perform alcohol oxidation (entry E2, Table ).
