A One-Pot Procedure to Prepare S-Protected 4-Iodothiophenols
摘要:
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.

A variety of S-thiophenol protectinggroups have been evaluated for the Heck reaction. Of these, the S-acetyl group appears to be the best suited for facile removal under mild conditions to provide the corresponding free thiols in high yields.
