Synthesis, crystal structure, and explosive decomposition of 1,2:5,6: 11,12:15,16-tetrabenzo-3,7,9,13,17,19-hexadehydro[20] annulene: formation of onion- and tube-like closed-shell carbon particles

We have reported that tribenzotetradehydro[14]annulene 1 undergoes topochemical polymerization that results in a novel polyannulenoenyne. In this connection, the `expanded` title compound 2a suggested itself as a promising candidate on route to unprecedented annulene-crosslinked polyenynes. We report the very different physical and chemical behavior of 2a, most importantly its explosive transformation to methane, hydrogen, and extensively ordered pure carbon. Present results give a clear validation of the notion that dehydroannulenes might be potential precursors to carbon allotropes. 28 refs., 1 fig.
