Several mesoionic compounds react with 2-tert-butylfulvene derivatives to form [4 pi+6 pi] and/or [4 pi+2 pi] cycloadducts. They undergo further fragmentation elimination or isomerization under the reaction conditions to give a variety of products including several condensed heterocycles which are isoelectronic with azulene. An oxazolium-4-olate, on contact with a small amount of air was found to form a tricyclic oxygenated dimer. (C) 1997 Elsevier Science Ltd.
