Mechanism for 2,4-Dinitrophenylhydrazone - YouTube

Webphenylhydrazone which isomerizes to the respective enamine (or 'ene-hydrazine'). After protonation, a cyclic [3,3]-sigmatropic rearrangement occurs producing an imine. The resulting imine forms a cyclic aminoacetal (or aminal), which under acid catalysis that eliminates NH3, resulting in the energetically favorable aromatic indole. how to sew elbow patches on a shirt
