pressure as in earlier procedure (alternatively, it was obtained
by extraction with benign solvent for relatively small scale re-
actions) as a colorless liquid (low melting solid); yield: 920 mg
(92%). The product was identified by comparison of its spectra
(1H and 13C NMR) with those of an authentic sample prepared
earlier. The ionic liquid was recycled in the same way as in ear-
lier experiment.

This procedure was followed for the conversion of all alco-
hols into the corresponding thioethers listed in Table 4. All
the products are known compounds and were easily identified
by comparison of their spectra with those of authentic samples.
This procedure was also followed for the transthioetherifica-
tion of ethers listed in Table 5 using 3 equivalents of tert-butyl
bromide and 2 equivalents of thiophenol for one equivalent of
ether. All the products in this series are also known compounds
and were easily identified by comparison of their spectroscopic
data with those of authentic samples.
