Procedure
2.0 ml of methylene chloride, 0.03 ml (0.42 mmol) of mercaptoacetic acid and 80 mg (0.39 mmol) of 2,6-di-tert-butyl-4-methylpyridine were charged in a flask, and 290 mg (0.38 mmol) of heptadecafluoro-n-octylphenyliodonium trifluoromethanesulfonate was added thereto in small portions while stirring at room temperature, followed by stirring for 20 minutes at room temperature. The resulting preciptiate was filtered, subjected to silica gel column chromatography and, after eluting iodobenzene with pentane, the desired product was eluted with diethyl ether. Diethyl ether was distilled off from the eluate to obtain heptadecafluoro-n-octylthioacetic acid as white crystals. A sample of the product was purified by gas chromatography. Yield, 88%.
