Target class: asymmetric hydrogenation catalyst Context triple: [Noyori asymmetric hydrogenation catalysts, instanceOf, asymmetric hydrogenation catalyst]
-
A.
organometallic catalyst
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.
-
B.
coordination catalyst
chosen
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.
-
C.
polymerization catalyst
A polymerization catalyst is a substance that accelerates and directs the chemical reaction in which small monomer molecules join to form long-chain polymers, often controlling polymer structure and properties.
-
D.
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).
-
E.
catalyst
A catalyst is an entity that accelerates or enables a process or reaction without being consumed or permanently altered in the transformation.
- 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.
