An N-heterocyclic carbene-catalyzed switchable reaction of 9-(trimethylsilyl)fluorene and aldehydes: Chemoselective synthesis of dibenzofulvenes and fluorenyl alcohols

An N-heterocyclic carbene-catalyzed synthesis of dibenzofulvenes and fluorenyl alcohols was developed. In the presence of 10 mol% NHC (1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) and 4 ? molecular sieves, 9-(trimethylsilyl)fluorene undergoes an olef

Synthesis of fluorenes via the palladium-catalyzed 5-exo-dig annulation of o-alkynylbiaryls

The direct palladium-catalyzed intramolecular hydro arylation of o-alkynylbiaryls proceeded in a highly stereoselective manner producing fluorenes 2, the products of 5-exo-dig cyclization, in excellent yields. The cascade intermolecular arylation, incorpo

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.
