The Symmetrical Cyclooctadienynes: 1,5-Cyclooctadien-3-yne and 1,3-Cyclooctadien-6-yne

Echter, Toni,Meier, Herbert

, p. 182 - 197 (2007/10/02)

Starting with 1,5-cycloctadiene (1) and cyclooctatetraene (2), respectively, the title compounds 16 and 17, highly strained members of the C8H8-series, can be generated in six or seven steps and isolated in pure state.Their stability and their chemical behaviour is discussed.Di- and oligomerisations on the one hand and Diels-Alder reactions on the other are mainly concerned. 16 and 17 are very reactive dienophiles; moreover 17 can also be used as a diene.
