Citronellal → (-)-Isopulegol

Participants

Reaction Steps

0.001 mmol zinc bromide is initially introduced into 70 ml toluene under an inert gas. The reaction solution is then temperature-controlled at 85° C. and 0.05 mol citronellal are metered into the reaction solution. The heterogeneous reaction mixture is then stirred at this temperature for 4 h. Thereafter, the reaction mixture is washed with 50 ml 15% strength sodium hydroxide solution and, after washing neutral, the solvent is removed from the reaction mixture under reduced pressure.
