Benzophenone, a material that is common in biomass and coal, resists pyrolysis up to 400 °C. However, when the compound is reduced with potassium metal in tetrahydrofuran (THF) followed by solvent removal, the C−H bonds, as well as the CO bond, ar

Vapor deposition has been used to create glassy materials with extraordinary thermodynamic and kinetic stability and high density. For glasses prepared from indomethacin or 1,3-bis-(1-naphthyl)-5-(2-naphthyl)benzene, stability is optimized when depos

Irradiation (lambda254 nm) of matrix-isolated 2,5-diiodothiophene (10) gives rise to IR bands assigned to ethynylthioketene (6). Diethynyl sulfide (3), which would form in the process of retro-Bergman cyclization of the incipient 2,5-didehydrothiophe

Electronic structures and rearrangement pathways of several C4H2S isomers are computationally investigated by methods based on coupled cluster theory and density functional theory. Six singlet C4H2S isomers lie within ca. 30 kcal/mol above butatriene

Irradiation (lambda = 670 or613 nm) of 4,5-benzodiazocycloheptatriene (15), matrix isolated in argon at 10 K, produces primarily 2,3-benzobicyclo[4.1.0]hepta-2,4,6-triene (9) accompanied by small amounts of triplet 4,5-benzocycloheptatrienylidene (2)

The anion radical of cyclooctatetraene (COT) must undergo a Jahn−Teller distortion from its ideal D8h symmetry. Both B3LYP/6-31+G* calculations and EPR observation have shown that the COT moiety in the anion radical of 1,2-dicarbo-tert-butoxycycloo

Solutions of 1,4-bis(dihydroquininyl)-anthraquinone {(DHQ)2AQN} in either hexamethylphosphoramide (HMPA) or liquid ammonia undergo a photoinduced electron transfer from the solvent to the (DHQ)2AQN. The resulting anion radical {(DHQ)2AQN•-} yields
