Target class: chiral ruthenium complex Context triple: [Noyori asymmetric hydrogenation catalysts, instanceOf, chiral ruthenium complex]
-
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.
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).
-
C.
coordination catalyst
A coordination catalyst is a substance, often a transition metal complex, that accelerates a chemical reaction by temporarily forming coordination bonds with reactants to lower the activation energy without being consumed.
-
D.
organometallic catalyst
chosen
An organometallic catalyst is a compound containing metal–carbon bonds that accelerates chemical reactions, often enabling selective and energy-efficient transformations in organic and industrial processes.
-
E.
transition metal
A transition metal is a d-block element that forms one or more stable ions with partially filled d subshells, often exhibiting variable oxidation states and catalytic properties.
- 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.
