TCI Practical Example: Electroreduction Using Hydrazine Monohydrate

Used Chemicals

Procedure

Trifluoroacetic acid (0.355 mL, 4.64 mmol, 11.6 eq.) was added to a solution of 1-Phenylpropargyl alcohol (52.9 mg, 0.40 mmol) and hydrazine monohydrate (500 mg, 10.0 mmol, 25 eq.) in methanol (5 mL) at room temperature. An RVC electrode was immersed in the solution and constant current electrolysis was performed at a current of 40 mA until an electrical flow of 45 F/mol was completed. Water (20 mL) was added to the reaction mixture and the aqueous layer was extracted with diethyl ether (20 mL, twice). The combined organic layer was dried over sodium sulfate and filtered. The solvent was removed under reduced pressure to give 1-phenyl-1-propanol as a colorless liquid (57.2 mg, >99% yield).

Experimenter’s Comments

The reaction mixture was monitored by UPLC.
The experiment was conducted in a fume hood because gas is produced during the reaction.
The reaction was carried out for about 8 hours.
IKA ElectraSyn 2.0 was used as an electrolytic apparatus in this experiment.

Analytical Data

1-phenyl-1-propanol

1H NMR (400 MHz, CDCl3); δ 7.39–7.26 (m, 5H), 4.59 (t, J = 6.4 Hz, 1H), 2.07 (br s, 1H), 1.88–1.70 (m, 2H), 0.92 (t, J = 7.2 Hz, 3H).

Used Chemicals

Procedure

Hydrazine monohydrate (275 mg, 5.5 mmol, 1.1 eq.) was added to 1,3-diphenyl-1,3-propanedione (1.12 g, 5.0 mmol) in EtOH (20 mL) at room temperature. The mixture was refluxed for 2 hours.Then water (80 mL) was added to the reaction mixture and precipitate was filtered to give 3,5-diphenyl-1H-pyrazole as a white solid (1.05 g, 95% yield).

Experimenter’s Comments

The reaction mixture was monitored by UPLC.

Analytical Data

3,5-Diphenyl-1H-pyrazole

1H NMR (400 MHz, DMSO-d6); δ 7.83-7.75 (m, 4H), 7.43-7.38 (m, 4H), 7.34-7.25 (m, 2H), 7.14 (s, 1H).

Procedure

Hydrazine monohydrate (0.267 mL, 5.5 mmol, 1.1 eq.) was added to a solution of 4-phenyl-3-butyn-2-one (0.707 mL, 5.0 mmol) in EtOH (20 mL) at room temperature and the mixture was refluxed for 4 hours. Then the solvent was removed under reduced pressure and the residue was purified by column chromatography (on silica gel, ethyl acetate:hexane = 0:1 - 1:1) to give 5-methyl-3-phenyl-1H-pyrazole as a pale yellow solid (684 mg, 86% yield).

Experimenter’s Comments

The reaction mixture was monitored by UPLC.

Analytical Data

5-Methyl-3-phenyl-1H-pyrazole

1H NMR (400 MHz, CDCl3); δ 7.71 (d, J = 8.0 Hz, 2H), 7.37 (t, J = 7.2 Hz, 2H), 7.32-7.28 (m, 1H), 6.35 (s, 1H), 2.30 (s, 3H).
