Chemistry of Z-2H-Heptafluorobut-2-ene 1 is surveyed; cycloaddition reactions occur with a variety of benzenoid compounds, in some cases leading directly to aromatics. Addition to cyclopentadiene, followed by eliminations of hydrogen fluoride and ethyne, lead to isomeric bistrifluoromethylcyclopentadienes. Nucleophilic reactions occur readily with oxygen, nitrogen and sulphur nucleophiles and aniline provides a quinoline synthesis. (C) 1998 Elsevier Science Ltd. All rights reserved.

On irradiation, dibenzo-7-silanorbornadienes with bulkysubstituents on silicon generated the corresponding crowded silylenes that dimerized to kinetically stabledisilenes in the absence of trapping agents. Dibenzo-7-silanorbornadienes also underwent a new type of photochemical isomerization competitively.
