In organic chemistry, '''thioenols''' (also known as '''alkenethiols''') are alkenes with a thiol group ({{chem2|\sSH}}) affixed to one of the carbon atoms composing the double bond (i.e. {{chem2|C\dC\sSH}}). They are the sulfur analogs of enols (hence the ''thio-'' prefix). Alkenes with a thiol group on both atoms of the double bond are called '''enedithiols'''. Deprotonated anions of thioenols are called '''thioenolates'''.
These structures exhibit tautomerism to give thioketones or thioaldehydes, analogous to keto–enol tautomerism of carbonyl structures.<ref>{{cite journal |title= The acid dissociation constant of triphenylethenethiol, a simple thioenol, and that of its oxygen–enol analog |first1= Yvonne |last1= Chiang |first2= A.
