2.3 The typical experiment of epoxides with H2S
In a typical run, styrene oxide
(1.0 g, 8.3 mmol) in a reaction vessel. The amount of catalyst is 0.1
Equiv. of the reactant and the condition of cycloaddition are 30 ÂșC and
2 hours. Pure mercaptan alcohol was obtained by thin-layer
chromatography (TLC) with petroleum ether (PE) and ethyl acetate (EA) as
eluent (3:1). The structures of mercaptan alcohol were verified by1H and 13C NMR spectra with
CDCl3 as solvent.
