2,3-Dihydro-1H-naphtho[1,8-cd]borinine as a Potent Precursor for Open-Shell Singlet B-Heterocycles

The reaction of naphthalene-1,8-diylbis[(trimethylsilyl)methanide] and dimethyl arylboronates afforded the corresponding 2,3-dihydro-1H-naphtho[1,8-cd]borinine as single diastereomers. Single-electron oxidation of the boron-containing heterocycles provided acenaphthylene through the generation boron-containing cyclic singlet biradicals.

Effect of potassium hydroxide on PAH formation during toluene incineration
Wei, Yu-Ling
, p. 509 - 521 (1998)
A laboratory-scale liquid-injection incinerator was used to incinerate toluene at 750°C and PAH emission was analyzed. The results indicate that the emission of solid-phase PAHs considerably increased when potassium hydroxide was added into a fuel-lean toluene flame; more potassium hydroxide resulted in more solid-phase PAHs. But this phenomenon was not observed for the fuel-rich toluene flame. The enhanced PAH formation is proposed as by-product of the partial oxidation or incomplete burning of soot in the secondary flame zone of the fuel-lean flame. It is suggested that reducing soot formation via potassium hydroxide addition may increase PAHs.

Radical-mediated gas-phase reactions play an important role in the conversion of methane under non-oxidative conditions into olefins and aromatics over iron-modified silica catalysts. Herein, we use operando photoelectron photoion coincidence spectroscopy to disentangle the elusive C2+ radical intermediates participating in the complex gas-phase reaction network. Our experiments pinpoint different C2-C5 radical species that allow for a stepwise growth of the hydrocarbon chains. Propargyl radicals (H2C?C≡C?H) are identified as essential precursors for the formation of aromatics, which then contribute to the formation of heavier hydrocarbon products via hydrogen abstraction–acetylene addition routes (HACA mechanism). These results provide comprehensive mechanistic insights that are relevant for the development of methane valorization processes.
RECORDING MATERIAL AND OPTICAL INFORMATION RECORDING MEDIUM
-
, (2016/06/01)
A recording material includes a dye-bonded polymer compound which contains a polymer compound to which a one-photon absorption dye is bonded, and a glass transition temperature of the recording material is higher than 200° C. An optical information recording medium includes a recording layer and an intermediate layer adjacent to the recording layer, and the recording layer contains the above-described recording material.
