Thiolan and Monothio-β-diketone Formation through the Use of a Nucleo-electrophilic Thiating Agent
LaLonde, Robert T.
, p. 401 - 402 (1982)
While the treatment of chalcone with anhydrous sodium polysulphide in anhydrous ethanol gave 2,4-dibenzoyl-3,5-diphenylthiolan, which was dehydrogenated to the corresponding thiophen for structure confirmation, the same two reactants in anhydrous 1,2-dimethoxyethane gave 1,3-diphenyl-3-thioxopropan-1-one.

A trisulfur-radical-anion (S3˙-)-triggered C(sp2)-H amination of α,β-unsaturated carbonyl derivatives with simple amines has been demonstrated. This protocol provides convenient access to a variety of synthetically valuable N-unprotected and secondary β-enaminones with absolute Z selectivity and tertiary β-enaminones with E selectivity. Mechanistic probe and electronic structure theory calculations suggest that S3˙- initiates the nucleophilic attacks via a thiirane intermediate.
Use of carbon-sulfur cathodes in electro-organic chemistry - Part 2 - Reactions with activated alkenes; evidence for a vicarious substitution specific of this type of electrode.
Guillanton, G. Le,Do, Q. T.,Simonet, J.
, p. 427 - 439 (2007/10/02)
The sulfur-carbon electrode, used as a cathode, appears to be an excellent source of nucleophiles which are good sulfuration reagents towards alkenes not substituted by leaving groups.However, the electrochemical reactions are often complex.It should be w
