Oxygenation of 3-methylindole catalyzed by cobalt(II) phthalocyanine attached to polyorganosiloxane Part 2. Mechanism for addition of oxygen to 3-methylindole

Abstract Oxygenation of 3-methylindole was catalyzed by cobalt(II)phthalocyanine (Co (II) Pc) attached to polyorganosiloxane. The mechanism for the addition of oxygen to 3-methylindole was examined by means of the reaction rate determined from the amount of oxygen consumption. The reaction rate ( V ) was given as follows: V = K [3-methylindole] [Co (II) Pc][O 2 ]. 3-Methylindole was concluded to be not only a substrate but also an oxidation inhibitor. The oxygenation was considered to proceed via a radical mechanism.
