Stereochemical Course of the Denitrogenation of Optically Active 9,10-Dihydro-5,6-diazalumibullvalene to Optically Active 3,4-Dihydrosemibullvalene

Askani, Rainer,Andermann, Thomas,Mueller, Karl Michael

, p. 1927 - 1938 (2007/10/02)

Thermal decomposition of optical active diazalumibullvalene derivative (+)-6 gives optical active dihydrosemibullvalene (+)-5.The absolute configurations of optical active 6 and 5 were determined by correlation to tricyclooctanone 9 and 2-cyclopentene-1-a
