Application


  • Cyclopentanone as a catalyst in stereoselective synthesis: Research highlighted the use of cyclopentanone in enhancing substrate stereoselectivity during the isothiourea-catalyzed conjugate addition of cyclic alpha-substituted beta-ketoesters to alpha,beta-unsaturated aryl esters, providing a pathway for precision in chemical synthesis. (Yuan et al., 2023).

  • Role in the synthesis of metal complexes: Cyclopentanone contributed to the synthesis, structural determination, and reactivity study of complex metal systems such as trindane and truxene, underscoring its utility in advanced organic synthesis and materials science. (Lock et al., 2023).

  • Impact on the properties of fluorinated derivatives: A theoretical study involving cyclopentanone examined the molecular properties of fluorinated derivatives, highlighting its importance in the development of high-performance solvents and pharmaceutical intermediates. (Tshepelevitsh et al., 2023).
