Target class: sigmatropic rearrangement Context triple: [Overman rearrangement, instanceOf, sigmatropic rearrangement]
-
A.
organic reaction
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.
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.
-
C.
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.
-
D.
named reaction in organic chemistry
chosen
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).
-
E.
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.
- F. None of above.
