A one-pot procedure to prepare S-protected 4-iodothiophenols

By means of non-aqueous reduction of pipsyl chloride followed by treatment with K2CO3 and then reacting with acetyl chloride or benzyl chloride, S-acetyl/benzyl -4-iodothiophenols were obtained in a one-pot procedure with yield as high as 90%. These S-protected arenethiols are very important intermediates to synthesize self-assembled molecular wires.
