A trimetallic zinc(II) complex and its catecholase activity

Synthesis and X-ray crystallographic characterization of a trimetallic zinc(II) complex [Zn3(L)2(fu)2] (1) [H2L = N,N-(salicyaldene)-1,3-diaminopropan-2-ol, fu = 2-furoate] reveal its distorted square pyramid geometry at the two terminal Zn(II) centres and distorted octahedral geometry at the central Zn(II). 1 behaves as an effective catalyst towards oxidation of 3,5-di-tert-butylcatechol in 1:1 methanol:dichloromethane mixture to its corresponding quinone derivative in aerial oxygen. The reaction follows Michaelis–Menten enzymatic reaction kinetics with turnover number (Kcat) 30.40 × 103 h−1.
