Light-Induced Intramolecular Iodine-Atom Transfer Radical Addition of Alkyne: An Approach from Aryl Iodide to Alkenyl Iodide

A light-induced intramolecular iodine-atom transfer radical addition was reported toward iodine-substituted fluorene derivatives. A thioxanthone derivative was employed as a visible light sensitizer for this 5-exo-dig exclusive radical addition, and the newly formed vinyl iodide compounds were further proved to be effective partners for several cross-coupling reactions.

Characterization of the Excited-State Reactivity of a Persistent Aryl-Substituted Allyl Free Radical

A family of stable aryl-substituted allyl radicals 1 (9H-fluoren-9-yl-9--9-ylidenephenylmethyls) has been characterized by electronic absorption spectroscopy, semiempirical (AM1) molecular orbital calculations, and cyclic voltammetry.Photolysis of 1a in aerated solvents that are poorer hydrogen atom sources than toluene resulted in oxygenation (ΦOX ca. 5 * 10-4) and cleavage products.A thermally reversible photocyclization mechanism is proposed to explain the oxygenation of 1a in inert solvents.Enhanced excited-state reactivity toward hydrogen and halogen atom donors was observed during the steady-state photolysis of 1a.Electron transfer from naphthalene to an excited state of 1a produces an extremely short lived (30 ps) 1a anion/naphthalene radical cation geminate pair.

Diels-Alder Reaction: 1,4-Cycloaddition of N-Aryl-maleimides to Alkylidene- and Arylidene-fluorenones and Synthesis of Some New Fluoranthene Derivatives

The 1,4-cycloaddition of different N-arylmaleimides (IIa-f) to alkylidene- and arylidene-fluorenones (Ia-c) leads to the formation of the diadducts, 7-substituted-5-aryl-4,6-dioxo-4H-3,3a,5,6,6a,7,10b-octahydrofluoranthenopyrrole-endo(3,10b)-N-arylpyrrolidino-2',5'-diones (IIIa-r).The fully aromatized fluoranthene derivatives (Va-i) have also been synthesised either by boiling III in nitrobenzene or by reacting the bromo-derivatives (V) with appropriate II.Reduction of III using LAH gives VIII.The structures of the isolated products have been confirmed by elemental analyses, molecular weight determination and spectroscopic data.
