rearrangement of 2,6-diethynyl-1,1′-biphenyl precursors to form polysubstituted pyrenes is described. This method is useful for the preparation of pyrenes with uncommon substitution patterns, and selective integration of functional groups at the 1-, 2-, 3-, 5-, 7- and 9-positions is demonstrated. pyrene - electrocyclic reactions - arenes - rearrangements - alkynes
