The primary product of flash vacuum pyrolysis of tetraphenylphthalic anhydride at 860 deg C/0.04 Torr is 1,2,3-triphenylbenzopentalene (74percent) and not 1,2,3- triphenylbiphenylene, as suggested by Fields and Meyerson (1968) for the product of pyrolysis

A series of π-extended pentalenes with fused naphthyl-ring systems in different geometries were synthesised via a cascade carbopalladation reaction between alkynes and gem-dibromoolefins. This novel methodology was applied both in an intermolecular and an intramolecular fashion to access pentalenes with new topologies. The relationship between the fusion pattern and the opto-electronic properties within the synthesised series was investigated by UV/vis spectroscopy and electrochemical techniques. Novel pentalene reactivity, leading to yet unprecedented derivatives, was also uncovered. The Royal Society of Chemistry 2014.

A carbopalladation cascade reaction of easily accessible gem-dibromoolefins and alkynes furnishes monobenzo- and mononaphthopentalenes. The new chromophores accessed by this short route exhibit small HOMO-LUMO gaps and redox amphoteric behavior with tunable redox potentials.
