1,2-dibromocyclopent-1-ene(CAS: 75415-78-0)

1,2-Dibromocyclopent-1-ene (CAS: 75415-78-0) is a colorless or pale yellow liquid with a molecular weight of approximately 216.03 g/mol. It has a low solubility in water but is soluble in organic solvents. Chemically, it is highly reactive, especially towards nucleophiles, and undergoes electrophilic addition reactions easily.

1,2-Dibromocyclopent-1-ene can be synthesized via bromination of cyclopentene using bromine in the presence of a Lewis acid catalyst, such as aluminum bromide. The reaction proceeds under anhydrous conditions to ensure high yield and selectivity.

1,2-Dibromocyclopent-1-ene finds applications in the pharmaceutical industry for the synthesis of certain intermediates, as well as in the polymer industry for the modification of polymers. It is also used in the production of sensors and semiconductors due to its unique reactivity.

When handling 1,2-dibromocyclopent-1-ene, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a well-ventilated area and handled under a fume hood. In case of a spill, immediate action should be taken according to the safety data sheet (SDS).
