Diethyl peroxide, physical properties

A mixture of arylboronic acid (1 1 mmol) and iodine (5 mol%) in 30% aqueous hydrogen peroxide (2 mL) was stirred in a reaction vessel at room temperature for 30-120 min. on completion of reaction (as monitored by TLC), the reaction mixture was diluted with water and extracted with diethyl ether. The organic layer was then washed with sodium thiosulfate solution, and dried over anhydrous sodium sulfate and filtered. The organic solvent was evaporated out under reduced pressure to furnish the crude phenolic product 2 (80-93% yield) which was purified by column chromatography on silica gel (ethyl acetate/hexane) followed by crystallization. Physical and spectral properties of all the products were found to be in close agreement with those reported for authentic samples.
