Thiiranes: One-pot Synthesis from Alkenes, and Catalytic Desulphurization
Capozzi, Francesco,Capozzi, Giuseppe,Menichetti, Stefano
, p. 4177 - 4180 (1988)
The reaction of bis(trimethylsilyl)sulphide with bromine at -78 deg C forms trimethylsilylsulphenyl bromide which reacts with alkenes to give thiiranes.Trimethylsilyl bromide and iodide catalytically desulphurize thiiranes to alkenes.

A catalyst-free, high-yielding conversion of oxiranes into thiiranes has efficiently been carried out by treatment with KSCN or thiourea at room temperature using polyethylene glycol (PEG-400) as the reaction medium.
An expeditious one-pot synthesis of thiiranes from α-halo ketones in solvent-free conditions using microwaves

Thiiranes are obtained in excellent yields and with high diastereoselectivity upon microwave irradiation of a mixture of α-haloketones, O,O-diethyl hydrogen phosphorodithioate and alumina-supported sodium borohydride in solvent-free conditions.
Selective Conversion of 2-Mercaptoalkanols to Thiirans with Orthocarbonates
Takata, Toshizaku,Endo, Takeshi
, p. 1818 - 1820 (2007/10/02)
Tetraalkyl orthocarbonates 1 were demonstrated to serve as potent cyclodehydrating agents for 2-mercaptoalkanols 2 to give the corresponding thiirans in good yields in acid-catalyzed reactions in aprotic solvents.Effect of catalysts, solvents, and alkyl substituents of 1 were examined.Activity of the acid catalysts depended on their acidity (pKa), and the strong Lewis acid BF3*OEt2 also had high catalytic activity.Effects of solvents and alkyl substituents of 1 were little observed.
