An efficient sulfenylation of aromatics using highly active quinone mono O,S-acetal bearing a pentafluorophenylthio group

A facile sulfenylation of various aromatic nuclei was achieved by use of the novel sulfenylation reagent, the quinone mono O,S-acetal bearing a pentafluorophenylthio group. It functioned below 0°C in the presence of a catalytic amount of TMSOTf.

Facile and efficient sulfenylation method using quinone mono-O,S-acetals under mild conditions

A novel sulfenylation method induced by aromatization of quinone mono-O,S-acetals is described. These sulfenylation reagents readily react with silyl enolethers or electron rich aromatic compounds to give sulfenylation products under mild conditions. In particular, O,S-acetal 2j, which possesses a pentafluorophenylthio function, is the most effective reagent from the standpoint of the adaptability for various substrates.
