  • Patent number: 9056822
    Abstract: PAH is subjected to C—H/C—B coupling using a specific boron compound, a palladium compound, and o-chloranil to produce a compound in which a C—H bond of the PAH is directly arylated regioselectively in a simple manner. When the substrate and the boron compound are appropriately selected, a larger PAH can also be obtained by further performing an annulation reaction after the coupling reaction. Similarly, when PAH is subjected to C—H/C—H cross-coupling using a specific aromatic compound, a palladium compound, and o-chloranil, a compound in which a C—H bond of the PAH is directly arylated regioselectively can be produced in a simple manner. When the substrate and the aromatic compound are appropriately selected in this case, a larger PAH can also be obtained by further performing an annulation reaction after the cross-coupling reaction.

  • Publication number: 20150097910
    Abstract: An optical scanning device including a light source and a rotating polygon mirror having a plurality of reflective surfaces scans a scan area of a surface in a main scanning direction with the light flux emitted from the light source and reflected by the rotating polygon mirror. All the light flux is reflected by a first reflective surface when light flux deflected by the rotating polygon mirror is directed onto a center position of the scan area, and a part of the light flux incident to the rotating polygon mirror is reflected by a second reflective surface adjacent to the first reflective surface when light flux reflected by the rotating polygon mirror is directed onto at least one end of both ends of the scan area and the light flux obliquely enters a plane perpendicular to a rotation axis of the rotating polygon mirror.
