Versuchsvorschrift
To solution of cyclohexanone (2.00 g, 20.4 mmol) and N,N-dimethylhydrazine (1.50 ml, 20.4 mmol) in ethanol (20 ml) was added a catalytic amount of toluene-4-sulfonic acid monohydrate. The reaction mixture was stirred at 70° C. for 72 h. The solvent was evaporated, and the residue was purified by Kugelrohr distillation (60-80° C., 5 mbar) to give the title compound (2.50 g, 87%) as colorless oil. MS m/e: 141 ([M+H]+)
