Cycloaddition von N-phenyltriazolindion an 1,5-dialkyl substituierte semibullvalene
Askani,Kirsten,Dugall
, p. 4437 - 4444 (2014/12/10)
Starting from bicyclo[3.3.0]octa-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 dihydrodiazatriquinacenes.
