Various ketones were smoothly converted into the corresponding α-tosyloxyketones with MCPBA and p-toluenesulfonic acid in the presence of a catalytic amount of ionic-liquid (IL)-supported PhI in room temperature ionic liquid, [emim]OTs. Moreover, the pres
Environmentally benign preparation of heteroaromatics from ketones or alcohols, with macroporous polystyrenesulfonic acid and (diacetoxyiodo)benzene, followed by thioamide, amidine, and 2-aminopyridine
