The discovery of the net‐cyclization of 1, 3‐hexadien‐5‐yne to benzene at temperatures
around 250° C was followed, particularly during the 1990s, by an increasing number of …

The discovery of the equilibration of alkynes with ylidenecarbenes at high temperatures has
been followed by increasing use of the reactivity of such carbenes in the synthesis of …

An energy barrier on the order of 60 kcal/mol is predicted for the 1, 2-shift of hydrogen atoms
in aryl radicals. Such rearrangements are, therefore, not expected to occur under ordinary …

By introducing antisextet dualists of sextet-resonant benzenoids that have only “full” and
“empty” rings as defined by Clar, it was possible to devise a simple algorithm for an …

The flow-vacuum pyrolyses of 5-methylene-5H-dibenzo [a, d] cycloheptene (11) were
studied by GC/MS at 1.33 mbar and temperatures between 750 and 1050° C. The major …

Condensation of seven aromatic aldehydes (1a–g) with glutacononitrile (2) gave 4-
(arylmethylidene) pent-2-enedinitriles (3a–g). Flash vacuum pyrolysis of the dinitriles (3a–g) …

This dissertation discusses several topics relating to the [N] phenylenes, including their
behavior under flash vacuum pyrolysis conditions, and the structural characterizations of …

UE Wiersum, while remembering Professor Robert Brown, describes a note on the
development of pyrolysis as a synthetic and mechanistic technique in organic chemistry. In …
