Two guanidine bases were used as organocatalysts for the synthesis of cyclic monothiocarbonates via the coupling reaction of carbonyl sulfide (COS) and epoxides. The systems proved to be efficient single-component, metal-free catalysts for the reaction of
Substituent effects on the control of cationic isomerization and polymerization of five-membered cyclic dithiocarbonates

The electrophilic reactions of five-membered cyclic dithiocarbonates were studied. They afforded the isomers and polymers depending on the substituents.

An equimolar reaction of 2-hexyloxirane with carbon disulfide in hexane was run in the presence of triethylamine under 800 MPa at 100 degC for 20 h, and gave 63percent of 4-hexy-1,3-dithiolan-2-one (3a), 21percent of 4-hexyl-1,3-dithiolane-2-thione (1a) and 5percent of 5-hexyl-1,3-oxathiolan-2-one (4a).Hexane, benzene, and diisopropyl ether were good solvents for the reaction.The reaction of a variety of oxiranes with carbon disulfide produced 1,3-dithiolan-2-one as the main products under 500 MPa at 100 degC for 20 h.Upon a reaction of 2-hexyloxirane with carbon disulfide, 5-hexyl-1,3-oxathiolane-2-thione (2a), and 2-hexylthiirane (5a) were produced during the first stage of reaction.The formation of 1a and 4a began immediately, whereas, the formation of 3a required a long induced period.A feasible mechanism for the formation of 3a is proposed to be a rearrangement of 2a in the presence of the triethylamine, free from carbon disulfide.
Conversion of Thiocarbonyl Compounds into their Corresponding Oxo-derivatives using Benzeneseleninic Anhydride

A series of thiocarbonyl compounds including xanthates, thioesters, thioureas, thiocarbonates, and thiones have been converted into their oxo-analogues by treatment with benzeneseleninic anhydride in tetrahydrofuran at room temperature.Except for readily enolised thiones where further oxidation can take place, the method works well and compares favourably with other literature procedures.One example of a selenocarbonyl ester was likewise converted efficiently into the corresponding ester.
