Free-radical Reaction of the Iron(II) Dichloroclathrochelate with Tetrahydrofurane Radical Derivatives: Synthesis and Structure of the Monotetrahydrofuryl-Containing Cage Complex

Abstract

Free-radical substitution of the chlorine atoms in the fluoroboron-capped iron(II) dichloroclathrochelate with tetrahydrofuran radical derivatives was studied. The reaction proceeds with high regioselectivity and yields the monofunctionalized macrobicyclic product. The molecular structure of this complex was determined both in solution and in the solid state using multinuclear NMR and the single-crystal X-ray diffraction.
