Target class: nucleophilic carbene intermediate Context triple: [Breslow intermediate in organocatalysis, instanceOf, nucleophilic carbene intermediate]
-
A.
carbene complex
A carbene complex is a coordination compound in which a metal center is bonded to a divalent carbon atom (a carbene), often stabilizing otherwise highly reactive carbene species and enabling diverse organometallic reactions.
-
B.
ylide reagent
A ylide reagent is a neutral molecule with adjacent positively and negatively charged atoms (typically phosphorus or sulfur bonded to carbon) that acts as a nucleophilic 1,2-dipole, commonly used to form alkenes or other functional groups in organic synthesis.
-
C.
alkylidene complex
An alkylidene complex is a coordination compound in which a metal center is double-bonded to a carbon atom that is also bonded to an alkyl group, forming a metal–carbon double bond (M=CR₂).
-
D.
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.
-
E.
named reaction reagent
A named reaction reagent is a specific chemical substance or mixture that is characteristically used to carry out a well-established, eponymous organic reaction under defined conditions.
- F. None of above. chosen
