- Reaktionen der Cyclopropene, V. Cyclooligomerisierungen von 3,3-Dialkylcyclopropenen an Palladium(0)-Katalysatoren
-
At phosphane free palladium(0) catalysts 3,3-dialkylcyclopropenes hept-1-ene (4)> are cyclooligomerised to give the trans-tricyclo2,4>hexane derivatives 6, 7, and 8, and the pentacyclo2,4.05,7.08,10>dodecane derivatives 10, 11, and 12.Contrary to this at triisopropylphosphane modified palladium(0) catalysts the tetracyclo2,4.05,7>nonane derivatives 14, 15, and 16 are formed selectively in more than 80percent yield.
