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.
