Eosin y catalyzed difunctionalization of styrenes using O2 and CS2: A direct access to 1,3-oxathiolane-2-thiones

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.

Lead(II) methyl xanthate [Pb(S2COMe)2] was synthesized and characterized by single crystal X-ray crystallography. The molecular structure showed a distorted tetrahedral geometry around Pb(II) with each monomeric unit linked with another through Pb???S interactions. The compound was used to prepare hexadecylamine capped PbS (HDA-PbS) and oleylamine capped PbS (OLA-PbS) nanoparticles. The PbS nanoparticles were indexed to the cubic PbS crystalline phase with particle sizes of 4.5–34.5 nm. The estimated optical bandgaps obtained from the tauc’s plots were 3.47 and 3.30 eV for HDA-PbS and OLA-PbS, respectively, which are blue shifted in comparison to bulk PbS. The photodegradation of methylene blue using PbS as photocatalyst shows that HDA-PbS have the best degradation efficiency of 77.70% after 240 min.

Four In(III) xanthate complexes, [In(S2COR)3] where R = Me, Et, iPr and sBu, respectively, were synthesized, characterized and subsequently used as single source molecular precursors via a solventless thermolysis route to obtain indium sulfide materials. By choice of precursor and reaction temperature crystalline powders of tetragonal In2S3, cubic In2S3 and cubic In2.77S4 were acquired. The phase identification and purity were conducted through examination of the experimental powder X-ray diffraction patterns relative to the simulated patterns for single X-ray crystal diffraction.
