<i>N</i>-Arylation of Benzimidazole with Arylboronate, Boroxine and Boronic Acids. Acceleration with an Optimal Amount of Water

The coupling of benzimidazole 1 with arylboronate, boroxine, and boronicacids is accelerated efficiently by the addition of an optimalamount of water. This coupling reaction proceeds in nearly quantitative yield at 30 °C under an atmosphere of air within 24 hours. Under these conditions, the reaction tolerates both electron-donating and electron-withdrawing substituents at the ortho-, meta, or para-positions
This invention relates to compositions and electroluminescent (EL) devices that have enhanced performance as a result of a novel class of anthracene derivatives used as host materials for a full range of color dopands. When using coumarin derivatives as color dopands in the anthracene derivatives in an EL device, the device performs a desirable light emitting efficiency and durability. The performance of the EL device can be further improved by using benazole derivatives as the electron transporting layer. The organic EL device of the present invention is useful in preparing display devices.
