Research Article

Oxidation of alcohols to aldehydes or ketones with a new highly active trivalent iodine compound, ABBX

Togo et al. have reported the preparation of a new highly active trivalent iodine compound, 1-acetoxy-5-bromo-1,2-benziodoxol-3(1H)-one (abbrev. ABBX), and its use for the oxidation of various alcohols to aldehydes or ketones with it. ABBX oxidizes aliphatic primary and secondary alcohols to the corresponding aldehydes and ketones in good yields by simple extraction of the reaction mixture. ABBX is soluble and shows high reactivity in solvents such as CHCl3, DMF and DMSO. 5-Bromo-2-iodobenzoic acid, formed as a co-product of this reaction, can be recovered by acidification of the aqueous layer.

Product Highlight

A Fluorescent Probe for Thiol-Specific Labeling

Bromobimane (mBBr) is a fluorescent probe linking specifically to thiol groups, which has a maximum absorption at about 390 nm with the labeled products producing fluorescence at about 480 nm (maximum wavelength).1) For example, mBBr has been applicable to label biological materials such as cysteine, glutathione, coenzyme A, and proteins including thiol groups.2-4) In protein research, it has been revealed that the status of disulfide bonds, formed by a combination of cysteine residues, regulates the functional activity of proteins (redox regulation). So proteomic analysis with the use of mBBr has been performed.5) Furthermore, mBBr-labeling has been applied to the analysis of proteins in food.6)
