Oxidase Studies of Substituted Catechols using Copper (II) Complex of Bis (2-benzimidazolylmethyl) ether

The synthesis of a Cu (II) complex [Cu (DGB) 2 (ClO4) (CH3COO)] of Bis (2-benzimidazolylmethyl) ether has been described. The copper (II) complex use as catalyst to carry out the oxidation of substituted Catechols (DTBC) in methanol using molecular oxygen as the oxidant. spectroscopic method has been used to determine the rate of reaction. The initial rate of formation of the product is found to be dependent on the amount of substrate employed. In the presence of dopamine and 3, 4-dihydroxy benzoic acid the catalyst do not show any catalysis. It means that the presence of dopamine and 3, 4-dihydroxy benzoic acid block the active sites of catalyst, which is responsible for the catalysis.
