Thioenol

In organic chemistry, thioenols (also known as alkenethiols) are alkenes with a thiol group (−SH) affixed to one of the carbon atoms composing the double bond (i.e. C=C−SH).

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.

These structures exhibit tautomerism to give thioketones or thioaldehydes, analogous to keto–enol tautomerism of carbonyl structures.
