General Description

3-ethyl-1-cyclopentene is a chemical compound with the molecular formula C8H14. It is a colorless liquid with a sweet odor, commonly used as a solvent in industrial applications. 3-ETHYL-1-CYCLOPENTENE is a cyclic alkene, meaning it contains a ring of carbon atoms with a double bond, and the ethyl group is attached to one of the carbon atoms in the ring. 3-ethyl-1-cyclopentene is flammable and may be harmful if inhaled, ingested, or brought into contact with the skin, so it should be handled with care and in accordance with safety regulations.

The Kinetics and Mechanism of Ring Opening of Radicals containing the Cyclobutylcarbinyl System

The kinetic parameters of β-fission of radicals containing the cyclobutylcarbinyl system have been determined by analysis of the mixtures obtained when suitable chloro-compounds are treated with tributylstannane.Under these conditions ring opening is irreversible and in the rigid bicyclic system (4) is under stereoelectronic control.For ring opening of cyclobutylcarbinyl radical (8) kf = 4.3 x 103 s-1 at 60 deg C, and the best values of the activation parameters appear to be ΔH(excit.) = 12.2 kcal mol-1 and ΔS(excit.) = -7.4 cal mol-1 K-1.Monocyclic systems undergo preferential fission of the more substituted βγ-bond.Methyl substituents at the α-, β-, or δ-positions have little effect but γ-substitution strongly enhances the rate of ring opening.The transition state is reactant-like and has a similar disposition of centres to that (1) for homolytic addition.
