How this entity was disambiguated
This entity first appeared as the object of triple T14187047 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Barton reaction
The Barton reaction is an organic photochemical transformation that converts nitrite esters into δ-nitroso alcohols via intramolecular hydrogen abstraction and radical rearrangement.
-
B.
Buchwald–Hartwig amination
The Buchwald–Hartwig amination is a palladium-catalyzed cross-coupling reaction that forms carbon–nitrogen bonds by coupling aryl (or vinyl) halides with amines, widely used in the synthesis of pharmaceuticals and fine chemicals.
-
C.
Robinson annulation reaction
The Robinson annulation reaction is a classic organic chemistry transformation that forms six-membered rings by combining a Michael addition with an intramolecular aldol condensation, widely used in the synthesis of complex cyclic molecules and natural products.
-
D.
Diels–Alder reaction
The Diels–Alder reaction is a fundamental organic chemistry cycloaddition that forms six-membered rings by combining a conjugated diene with a dienophile in a single, stereospecific step.
-
E.
Norrish reaction
The Norrish reaction is a photochemical process in organic chemistry involving the cleavage and rearrangement of carbonyl compounds under ultraviolet light, fundamental to understanding photodegradation and radical mechanisms.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
