Abstract
2-Methyl-(Ia), 2-phenyl-(Ib), 3-methyl-2-cyclohexenone (Xa) and 2-cyclohexenone (Xc) were reacted with equivalent mole of sodium azide in polyphosphoric acid. In all cases, 2-amino-2-cyclohexenone derivatives were yielded as abnormal reaction products. In the cases of Ia and Ib, migration of the methyl and the phenyl group to the position 3 was observed accompanied by the simultaneous introduction of an amino group at the position 2, respectively.
