The twisted 3,3′-diiodo-2,2′,6,6′-tetramethoxybiphenyl-4, 4′-dicarboxylic acid (DIDA) was designed and synthesized for the in situ generation of Bis-IBX and catalytic oxidations. The seemingly better solubility of the in situ-generated Bis-IBX and the attenuated reactivity arising from its unique structural features and methoxy substituents allowed the catalytic oxidation of activated alcohols selectively using DIDA/oxone. Chemoselective oxidations were demonstrated for substrates containing two different hydroxy groups. Furthermore, the unique reactivity of DIDA was demonstrated for sequential oxidation reactions of 1,4- and 1,6-diols to give lactones catalytically in respectable yields.

Halogenation of Phenols and Phenyl Ethers with Potassium Halides in the Presence of 18-Crown-6 on Oxidation with m-Chloroperbenzoic Acid
Srebnik, Morris,Mechoulam, Raphael,Yona, Irene

Several types of phenyl ethers have been monobrominated in the ring in good yields with potassium bromide in the presence of 18-crown-6 on oxidation with m-chloroperbenzoic acid.Monoiodination takes place with both phenyl ethers and free phenols when potassium iodide is employed.
