Expeditious microwave-assisted thionation with the system PSCl 3/H2O/Et3N under solvent-free condition

(Chemical Equation Presented) A novel thionation protocol for carbonyl compounds, with the system PSCl3/H2O/Et3N has been discovered. Clean, rapid, and efficient synthesis of a variety of thiocarbonyl compounds such as thioamides, thiolactams, thioketones, thioxanthones, and thioacridone can be achieved through this simple and convenient method under solventless condition with microwave irradiation.

Synthetic Sulfur Carotenoids III: Carotenoid Thiones - First Preparation and Spectroscopic Properties

The preparation of carotenoid thiones has been investigated, β,β-Caroten-4-thione, 4'-thioxo-β,β-caroten-4-one and 3'-thioxo-4',5'-didehydro-4',5'-retro-β,β-caroten-3-one were synthesized from echinenone, canthaxanthin and rhodoxanthin respectively.Charac

Bis(trimethylsilyl)sulfide based thionation of carbonyl compounds: Synthesis of thioketones

A wide range of thioketones may be conveniently obtained by silyl triflate promoted bis(trimethylsilyl)sulfide thionation of ketones.

MECHANISM OF OXIDATION OF α,β-UNSATURATED THIONES BY SINGLET OXYGEN

Photo-oxidation of α,β-unsaturated thiones yields the corresponding ketones as the only product.Studies carried out three systems, namely thioketones, α,β-unsaturated thiones and thioketenes, have revealed that there exists a similarity in their mechanism of oxidation.It has been suggested that the thiocarbonyl chromophore is the site of attack by singlet oxygen in α,β-unsaturated thiones and that the adjacent C-C double bond is inert under these conditions.Absence of sulphine during the oxidation of α,β-unsaturated thiones is attributed to the electronic factors operating on the zwitterionic / diradical intermediate.While α,β-unsaturated ketones are poorly reactive, α,β-unsaturated thiones are highly reactive toward singlet oxygen.
