Beschreibung

Anwendung

Potassium hydroxide on alumina (KOH/AL₂O₃) can be employed as a base catalyst:

• For the dehydrogenation of cyclic hydrocarbons (cycloolefins, cycloparaffins, and alkyl aromatics).
• To prepare pyridazine derivatives from 1,2-dicarbonyls, and hydrazine hydrate under microwave (MW) irradiation.
• In the total synthesis of natural product (-)-varitriol and (-)-3′-epi-varitriol (an isomer of (-)-varitriol) as potent antitumor agents.
