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.

Self-assembly of a trigonal building subunit with diaminotriazines (DAT) functional groups leads to a unique rod-packing 3D microporous hydrogen-bonded organic framework (HOF-3). This material shows permanent porosity and demonstrates highly selective separation of C2H2/CO2 at ambient temperature and pressure.
