Mechanism and inverse primary kinetic isotope effect in the reaction of fluorenylidene with 3-deuteriocyclohexene
Abstract
3-(9′-Fluorenyl)cyclohexene from the reaction of fluorenylidene with cyclohexene is formed by way of the fluorenyl-cyclohexenyl geminate radical pair; for the hydrogen abstraction leading to this radical pair, kH/kD≃ 0·78.
