A highly reactive molecule containing a divalent carbon atom, examples of which occur as intermediates in some organic reactions.
〔化〕卡宾，碳烯
Example sentencesExamples
This reaction has become synthetically useful since the discovery of various well-defined transition metal carbene complexes which can catalyse alkene metathesis.
We have since shown that this type of conical intersection structure is general for other alkene systems leading to carbene formation and cis-trans isomerization where possible.
So here we have the personal opinion of a professor in chemistry, famous for his work on carbenes, commenting on evolution and at the same time his title evolved into professor of biochemistry.
It is only in reactions with transition metals that carbenes are stable, due to the distribution of electrons within the structure formed.
