Yield:-

Reaction Conditions:

with [FeIV (N,N-bis(2-pyridylmethyl)-1,2-di(2-pyridyl)ethylamine)(O)](ClO4)2 in acetonitrile at 24.84;Kinetics;Inert atmosphere;

Steps:

2.2 Stoichiometric oxidations
General procedure: [FeII (asN4Py)(CH3CN)](ClO4)2 complex (2.00×10-3M) was dissolved in acetonitrile (1.5mL), then iodosobenzene (2.4×10-3M) was added to the solution. The mixture was stirred for 40min then excess iodosobenzene was removed by filtration. Substrate (1.00×10-2-4.00×10-2M) was added to the solution and the reaction was monitored with UV-vis spectrophotometer at 705nm (ε=400M-1cm-1) (Table 1 ). The characterization of the product 4,4′-dihydroxy-3,3′,5,5′-tetra-tert-butylbiphenyl (H2DPQ) based on previously described methods [6c].
