Cycloheptene was used in one-pot synthesis of 1,2/3-triols from the allylichydroperoxides catalyzed by zeolite-confined osmium(0) nanoclusters. It is a raw material in organic chemistry and a monomer in polymer synthesis. Copper (1) triflate catalyzes the photodimerization of the simple nonconjugated unstrained olefins, cyclopentene, cyclohexene, and cycloheptene, but not cyclooctene or acyclic olefins.
