The synthesis of cyclic dithiocarbonates via photo-difunctionalization of the C–C double bond of styrene and aryl aldehydes via photo-oxidative cleavage of the C–C double bond of styrene was accomplished in the presence of CdS NPs at room temperature in air atmosphere under visible light irradiation without using any external oxidant. Some of the special advantages of these processes are the use of CdS NPs as a simple, accessible, safe, and visible-light-induced reusable catalyst, as well as the use of air as an easily attainable, inexpensive, and harmless oxidant, styrene as a readily accessible substrate, and visible-light as a renewable and safe energy source.

Alkali metal alkoxides were studied as catalysts for the addition of CS2 to epoxides. A screening of several commercially available alkoxides revealed lithium tert-butoxide as an active and selective catalyst for this reaction. The influence of different reaction parameters as well as the substrate scope under optimized reaction conditions has been studied. Terminal and highly substituted epoxides as well as thiiranes were converted. In total 28 products were prepared and isolated in yields up to 95%. Notably, the reactions were performed under mild conditions without additional solvents. The regio- and stereoselectivity of the reaction has been studied e.g. by converting (R)-styrene and (R)-propylene oxide. Moreover, the test reaction was monitored by 13C NMR and a plausible mechanism for the conversion of terminal and internal epoxides is given. This proposal is in agreement with the observed regio- and stereoselectivity of the reaction.

Visible light promoted straightforward highly regioselective synthesis of 1,3-oxathiolane-2-thiones (cyclic dithiocarbonates) starting directly from styrenes, CS2 and air (O2) is reported. The protocol utilizes eosin Y as an organophotoredox catalyst and clean resources like visible light and air (O2) as sustainable reagents at room temperature in a one-pot procedure. Additionally, the approach is advantageous in terms of step economy as it skips the prefunctionalization of styrenes to oxiranes, which has been inevitable in commonly used syntheses of 1,3-oxathiolane-2-thiones.

Cyclic dithiocarbonates were prepared in good yield and excellent selectivity through an environmental acceptable methodology involving the reaction of substituted epoxides with carbon disulfide under hydrotalcite catalysis. The catalyst can be recovered by filtration and reused several times. Georg Thieme Verlag Stuttgart.
