Description

Application

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.
