摘要：

Dioxygenolysis of 3-methylindole catalyzed by a series of cobalt(II) Schiff base complexes electronically and sterically designed gives 2-(N-formylamino) acetophenone as the sole product, but the reaction rate depended largely on the structure of the complex:the more positive SIGMA-degrees (Co(II)/Co(III)) brings about the more catalytic activity. Steric hindrance of coordination of the substrate to the catalyst retards the reaction.
