CYCLOADDITION VON N-PHENYLTRIAZOLINDION AN 1,5-DIALKYL SUBSTITUIERTE SEMIBULLVALENE
Askani, R.,Kirsten, R.,Dugall, B.
, p. 4437 - 4444 (2007/10/02)
Starting from bicycloocta-3,7-diones, several 3- and 7-substituted semibullvalenes were prepared.Cycloaddition of N-phenyltriazolindione to some of these semibullvalenes lead with rearrangement of the carbon skeleton to dihydrdioazatriquinacenes.De
