This article is about the prefix in organic chemistry. For other uses, see Thio (disambiguation).
The prefixthio-, when applied to a chemical, such as an ion, means that an oxygen atom in the compound has been replaced by a sulfur atom. This term is often used in organic chemistry. For example, from the word ether, referring to an oxygen-containing compound having the general chemical structureR−O−R′, where R and R′ are organic functional groups and O is an oxygen atom, comes the word thioether, which refers to an analogous compound with the general structure R−S−R′, where S is a sulfur atom covalently bonded to two organic groups.[1] A chemical reaction involving the replacement of oxygen to sulfur is called thionation or thiation.
Thio- can be prefixed with di- and tri- in chemical nomenclature.
The word derives from Ancient Greekθεῖον (theîon) 'sulfur' (which occurs in Greek epic poetry as θέ(ϝ)ειον, théweion and may come from the same root as Latinfumus (Indo-Europeandh-w) and may have originally meant "fumigation substance".)
