Target class: pericyclic reaction Context triple: [Diels–Alder reaction, instanceOf, pericyclic reaction]
-
A.
organic reaction
chosen
An organic reaction is a chemical transformation involving organic compounds, where bonds between carbon and other atoms are broken and formed to yield new molecular structures.
-
B.
named reaction in organic chemistry
A named reaction in organic chemistry is a specific, well-characterized chemical transformation between organic molecules that is widely recognized and referred to by the name of its discoverer(s) or originator(s).
-
C.
reaction intermediate
A reaction intermediate is a transient, unstable species formed during a chemical reaction that exists between reactants and products and cannot usually be isolated under normal conditions.
-
D.
nucleophilic carbene intermediate
A nucleophilic carbene intermediate is a reactive species featuring a divalent carbon atom with a lone pair and partial negative character that can donate electron density to electrophilic centers during chemical transformations.
-
E.
carbene-derived species
Carbene-derived species are reactive intermediates or products formed from carbenes through insertion, addition, rearrangement, or dimerization reactions, often featuring divalent carbon centers or their transformed derivatives.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
