efficient, and recyclable bifunctional catalysts bearing ionic liquid supported (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) and iodoarene moieties were developed and used for environmentally benign catalytic oxidation of alcohols. The reactions using peracetic acid as a green and practical co-oxidant afforded the corresponding carbonyl compounds in high yields under mild conditions and convenient work-up

Evidence is presented that the reaction of mercury(II) oxide–iodine with olefins in aprotic solvents proceeds through ‘iodine oxide’. From a study of the products, which include rearranged carbonyl compounds, vinyl iodides, and 2,2′-di-iodo-ethers, and from an investigation of the reactions of epoxides and iodohydrins with morcury(II) oxide–iodine, it is concluded that ‘iodine oxide’ addition occurs

The present invention relates to a method for simultaneously qualitatively and quantitatively analyzing aldehyde and/or ketone compounds in a short time using an optimal TLC plate, proportion of developing solvent, sample amount, and the like. By providing the optimal conditions for using TLC, the analysis result equivalent to a conventional analysis result can be obtained in a shorter time.
