Abstract: Crowned Schiffs base cobalt(Ⅱ) complex 1c and its analogues 1a and 1b were synthesized and their catalytic activities in cumene oxidation to cumyl hydroperoxide have been compared. The results showing that complex 1c being superior to its analogues in catalytic activity are explained in terms of their oxygen adduction constants.

Key words: crown ether, Schiff base, cobalt complex, synthesis, catalytic oxidation
