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

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

DENITROGENIERUNG VON OPTISCH AKTIVEM 9,10-DIHYDRO-5,6-DIAZALUMIBULLVALEN

Thermal decomposition of optically active title compound 1 yields optically active 2.Denitrogenations of 6 and 7 lead to semibullvalenes 8 and 9 respectively as the major products.These results indicate a concerted nitrogen expulsion.
