Abstract

Various ketones were converted to the corresponding α-tosyloxyketones with mCPBA and p- toluenesulfonic acid in the presence of a catalytic amount of iodobenzene. Moreover, secondary alcohols were directly converted to the corresponding α-tosyloxyketones using mCPBA and catalytic amounts of iodobenzene and potassium bromide, followed by treatment with p-toluenesulfonic acid in a one-pot manner. Poly (4-iodostyrene) could be ...
