What is Thial?
[[File:Thial-2D-general-structural-formula.png|thumb|right|150px|General structure of a thial]] A '''thial''', or '''thioaldehyde''', is any [[molecule]] with the [[functional group|group]] RC(S)H. It is like an [[aldehyde]] with the [[oxygen]] atom changed with a [[sulfur]]. The sulfur has a [[double bond]] to [[carbon]]. It also keeps two [[lone pair]]s. Thials are very reactive because they are very good [[electrophile]]s. It is difficult to make one, because they will react with themselves as soon as they are formed. They can do [[Diels-Alder reaction]]s very quickly. However, if [[steric effects|bulky]] R groups are used, the thial might be more stable. If the H is changed with another R group, then the molecule is called a [[thioketone]]. These are more stable. {{Functional group}} [[Category:Functional groups]] [[Category:Organosulfur compounds]]
