Formation of cyclopropanes by homolytic substitution reactions of 3- iodopropyl radicals: Preparative and rate studies

Article abstract of DOI:10.1016/S0040-4020(98)01144-2

Reduction of 2-substituted 1,3-diiodopropane derivatives with tin hydride provides substituted cyclopropanes. The reaction occurs through a homolytic substitution of the 3-iodopropyl radical, which has a rate constant of about 5 x 10⁵ s^-1 at 80°C.
