実験手順

To 9-fluorenone hydrazone (9.7 g, 0.05 moles) in 1,2-dichloroethane (50 ml) together with 1,1,3,3-tetramethylguanidine (26.4 ml) and iodine (2 ml, 1% w/v solution) was added peracetic acid solution (11.4 ml, 1.27 × 0.05 moles) over 25 minutes at 10° - 15°. The orange solution was stirred for 15 minutes at 15°, washed with water (5 × 250 ml) and made up to 250 ml in a volumetric flask. An aliquot (50 ml) treated with excess acetic acid yielded 193 ml gas corrected to NTP which corresponded to a 86.2% yield of diazoalkane.
