Tetraphenylene is a chemical compound from the group of polycyclic aromatic hydrocarbons .
Extraction and presentation
Tetraphenylene can be obtained by reacting biphenylmagnesium bromide with copper (II) chloride or biphenyllithium with cobalt or nickel chloride.
The preparation from biphenylene with a catalyst such as nickel dicarbonyl bis (triphenylphosphine) is also possible.
properties
Tetraphenylene is a colorless solid. It is a non-chiral molecule, but it can easily be converted into an unsymmetrical form.
