1,3-Dibenzylimidazolidine-2-thione [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2012
In the title compound, C17H18N2S, the imidazolidine ring adopts a twisted conformation. In the crystal, molecules are linked by slipped π–π interactions between the benzene rings of neighbouring molecules [centroid-to-centroid distance = 3.903 (2) Å].

Thione photochemistry. Dual pathways in aralkyl thione cyclizations [PDF]

open access: yesCanadian Journal of Chemistry, 1981
It is shown that aralkyl thiones, which possess an oxygen atom at the δ position in the side chain, can therefore not undergo the preferred δ insertion, and insert at the γ and ε positions. Although ε insertion occurs only from the 1(π,π*) state, γ abstraction (followed by cyclization or cleavage) occurs from both 1(π,π*) and 3(n,π*) states.

Synthesis and Reactivity of 3H-1,2-dithiole-3-thiones

open access: yesMolecules, 2021
3H-1,2-Dithiole-3-thiones are among the best studied classes of polysulfur-containing heterocycles due to the almost explosive recent interest in these compounds as sources of hydrogen sulfide as an endogenously produced gaseous signaling molecule.

Dihydropyrimidine-thiones and clioquinol synergize to target beta-amyloid cellular pathologies through a metal-dependent mechanism [PDF]

open access: yes, 2017
The lack of therapies for neurodegenerative diseases arises from our incomplete understanding of their underlying cellular toxicities and the limited number of predictive model systems.
