Target class: organometallic catalyst Context triple: [Ziegler–Natta catalysts, instanceOf, organometallic catalyst]
-
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.
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.
-
D.
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.
-
E.
organic compound
An organic compound is a chemical substance that contains carbon atoms covalently bonded to other elements, typically hydrogen, and often includes additional elements such as oxygen, nitrogen, sulfur, or halogens.
- F. None of above. chosen
