Thiopyrylium is a cation with the chemical formula C5H5S+. It is analogous to the pyrylium cation with the oxygen atom replaced by a sulfur atom. Thiopyrylium salts are less reactive than the analogous pyrylium salts due to the higher polarizability of the sulfur atom. Among the chalcogenic 6-membered unsaturated heterocycles, thiopyrylium is the most aromatic, due to sulfur having the similar Pauling electronegativity as carbon and only a slightly higher covalent radius. In water, thiopyrylium reacts to it and forms a mixture of and . Thiopyrylium salts can be synthesized by hydrogen abstraction from thiopyran by a hydride ion acceptor, such as . The thiopyrylium analogue of 2,4,6-trisubstituted pyrylium salts can be synthesized by treatment with sodium sulfide followed by precipitation with acid. This reaction causes the oxygen atom in the pyrylium cation to be substituted with sulfur. (Wikipedia).

Synthesizing Sulfur Dichloride: A Noxious Liquid That You DON'T WANT | Thionyl Chloride (Part 1)
Sulfur chlorides are both beautifully fascinating and horrendously vile. Today, we'll be synthesizing sulfur dichloride: a cherry-red liquid that is now my least favorite chemical to work with. Not only does it reek like death, but it also coats everything it touches in a layer of sulfur t
