Dimethyl 2-arylcyclopropane-1,1-dicarboxylates on heating with GaCl3 undergo dimerization to afford arylnaphthalenes or phenanthrenes. A possible reaction mechanism including elimination of two dimethyl malonate molecules was proposed, dimethyl malonate gallium complex Ga3+[H2C(CO2Me)2]3(GaCl4-)3 was isolated and characterized by X-ray diffraction analysis.

This work reports a novel and efficient protocol for the synthesis of 2-phenylnaphthalenes from styrene oxides using a recyclable ionic liquid. The ionic liquid N-methyl-2-pyrrolidone hydrogensulfate [HNMP]+HSO4- played the dual role of a catalyst and a solvent. It efficiently constructs 2-phenylnaphthalene and its derivatives in excellent yields with much simplicity in the operation. The present protocol has higher atom efficiency and wider substrate applicability. The [HNMP]+HSO4- has been effectively recycled for up to five consecutive cycles without appreciable loss in its activity.

Page/Page column 79-80, (2010/11/28)
The present invention provides a novel anthracene derivative, a method for preparing the same, and an organic electronic device using the same. The anthracene derivative according to the invention can function alone as a light emitting host, in particular, as a blue host in an organic electronic device. Further, the anthracene derivative according to the invention can also function as a hole injecting or hole transporting material, an electron injecting or electron transporting material, or a light emitting material in an organic electronic device including a light emitting device. Therefore, the organic electronic device according to the present invention shows excellent characteristics in efficiency, drive voltage and stability.
