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][O2]. 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.
