Application

1-Methylcyclopentene can be used as:
  • A probe molecule in the synthesis of alkenyl carbenium ions via adsorption on zeolite Y.
  • A model olefin compound in the kinetic study of hydrogenation of olefins using various catalytic systems.
  • A reactant to synthesize 1,2,3-trisubstituted benzocyclopentenes by reacting with β-disulfonyl iodonium ylides.
