Thiirane was readily generated from 2-mercaptoethyl trifluoroacetate or pentafluoropropionate by the intramolecular elimination of the perfluorocarboxylic acid with triethylamine.Alkyl benzyl sulfides were also prepared from benzyl trifluoroacetate or pentafluoropropionate and alkanethiols by the intermolecular elimination of the perfluorocarboxylic acid.

We have designed new imine-functionalized graphene oxide (IFGO) through post synthetic modifications involving co-condensation of 3-aminopropyltriethoxysilane with graphene oxide basal plane containing hydroxyl and epoxy functional groups, followed by Schiff base condensation reaction with 2,6-diformyl-4-methylphenol and impregnation of copper(ii) to it through covalent attachment (Cu-IFGO). Powder X-ray diffraction, N2 sorption analysis, FT-IR, HR-TEM, FE-SEM and TGA/DTA analysis are employed to characterize the materials. The IFGO material exhibits good CO2 storage capacity of 8.10 mmol g-1 (35.64 wt%) and 2.10 mmol g-1 (9.24 wt%) at 273 K and 298 K temperature, respectively, up to 3 bar pressure, suggesting its potential application in environmental clean-up. Also, Cu-IFGO showed high catalytic activity in microwave-assisted one-pot three-component C-S coupling reactions for a diverse range of aryl halides with thiourea and benzyl bromide in aqueous medium to obtain aryl thioether products (maximum yield 86%), which are derivatives of natural products. Moreover, having imine and hydroxyl groups in functionalized graphene oxide, the grafted Cu(ii) chelated at the graphene oxide surface so strongly that it could not be leached out from the material during the course of the coupling reaction. Thus, it displayed very small decrease in product yield up to the sixth reaction cycle suggesting a sustainable future of this Cu(ii)-grafted catalyst.

A new, mild, and novel method is described for the efficient deoxygenation of sulfoxides to their corresponding sulfides with 1,3-dithiane at room temperature in the presence of catalytic amounts of N-bromosuccinimide (NBS), 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TABCO), or Br2 as the source of electrophilic bromine.
