Definition of Cyclobutadiene. Meaning of Cyclobutadiene. Synonyms of Cyclobutadiene

- Cyclobutadiene is an organic compound with the formula C4H4. It is very reactive owing to its tendency to dimerize. Although the parent compound has not...
- cyclopentadienyl cation (C). The prototypical example of antiaromaticity, cyclobutadiene, is the subject of debate, with some scientists arguing that antiaromaticity...
- agent is used in large excess. A famous example is the detection of cyclobutadiene released upon oxidation of cyclobutadieneiron tricarbonyl. When this...
- Rule. Whereas benzene is aromatic (6 electrons, from 3 double bonds), cyclobutadiene is not, since the number of π delocalized electrons is 4, which of course...
- non-aromatic ([8] and [10]annulene), or anti-aromatic (cyclobutadiene, [4]annulene). Cyclobutadiene is the only annulene with considerable antiaromaticity...
- solvents. It has been used in organic chemistry as a precursor for cyclobutadiene, which is an elusive species in the free state. Cyclobutadieneiron tricarbonyl...
- tetrakis(tert-butyl)cyclobutadiene: This approach took advantage of the observation that the tetrahedrane and the cyclobutadiene could be interconverted...
- of ladderane synthesis are outlined below. The dimerization of two cyclobutadienes can generate both the syn and anti ladderane products depending on...
- special stabilization beyond normal delocalization effects, while C4H4 (cyclobutadiene) actually experiences a special destabilization.[citation needed] Molecular...
- In practice, such molecules distort from planar regular polygons. Cyclobutadiene (C4H4) with four π electrons is stable only at temperatures below 35 K...
