===Diels-Alder reactions===

The [[Diels-Alder reaction]] is perhaps the most important and commonly taught cycloaddition reaction. Formally it is a [4+2] cycloaddition reaction and exists in a huge range of forms, including the [[inverse electron-demand Diels–Alder reaction]], [[Hexadehydrohexadehydro Diels-AlderDiels–Alder reaction]] and the related [[alkyne trimerisation]]. The reaction can also be run in reverse in the [[retro-Diels–Alder reaction]].

Reactions involving heteroatoms are known;, including the [[Azaaza-Diels–Alder reaction|aza-Diels–Alder]] and [[Imine oxo-Diels–Alder reaction]].
