  名称：

  Stereoselective synthesis of both (E)- and (Z)-1,2,4-heptatrien-6-ynes. Formation of an .alpha.,3-dehydrotoluene biradical, trapping by an intramolecular carbon-carbon double bond, and decay of the resulting new biradical via an intramolecular route

  摘要：

  Condensation between conjugated allenic aldehydes 3 and gamma-(trimethylsilyl)allenylboranes 2 followed by the Peterson olefination reaction afforded enyne-alleness 7 and 8. On heating, 8c underwent a sequence of intramolecular transformations through biradical intermediates.
