Template:Chembox Footer/trackingTemplate:Short description

Indoline is an aromatic heterocyclic organic compound with the chemical formulation C8H9N. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring. The compound is based on the indole structure, but the 2-3 bond is saturated. By oxidation/dehydrogenation it can be converted to indole.[1][2]

Indoline can be produced from the reaction of indole, zinc and 85% phosphoric acid.[3] It was used to make Indocaine.
