- via SNAr mechanisms. Aryl halides often react via the intermediacy of benzynes. Chlorobenzene and sodium amide react in liquid ammonia to give aniline...
- reactive aryne, benzyne. It is obtained by diazotization of the amine group using sodium nitrite which eliminates nitrogen and CO2 giving benzyne as an intermediate...
- predicted for spin-1 Heisenberg chain. A related class of biradicals are para-benzynes. Other studied biradicals are those based on pleiadene, extended viologens...
- means of chemical trapping Radical Carbene Carbocation Carbanion Carbyne Benzyne (an aryne) Carbenoid Ion-neutral complex Keto anions Nitrenes Oxocarbenium...
- formula C6H4 (molar m****: 76.10 g/mol, exact m****: 76.0313 u) may refer to: Benzyne Phenylene Triafulvalene, or cyclopropenylidenecyclopropene Butalene This...
- synthesized in various ways. One method is trimerization of benzyne. Another method involves trapping benzyne with a biphenyl derivative. Triphenylene is more resonance...
- converted to chlorobenzene by nucleophilic aromatic substitution via a benzyne intermediate. It is treated with aqueous sodium hydroxide at 350 °C and...
- and diynes are used instead of alkenes and dienes, forming an unstable benzyne intermediate which can then be trapped to form an aromatic product. This...
