A new protocol for the direct reductive cobalt-catalyzed arylation of benzyl chlorides has been developed in order to form functionalized diarylmethanes. A variety of reactive groups either on the aryl or the benzyl halide was employed. This represents the first cobalt-catalyzed reductive cross-coupling which does not require any ligand and pyridine. A reaction pathway is proposed involving a radical benzyl species. (Figure presented.).

Paragraph 0121; 0122, (2017/01/02)
The present invention relates to a method for preparing an anthracene derivative by using a bismuth catalyst. The invention relates to a method for preparing an anthracene derivative simply and efficiently by using a bismuth catalyst and an acid additive. The preparation method allows obtaining a target material in a short time at a high yield by using a bismuth catalyst and an acid additive. Then, the prepared anthracene derivative may be used in a synthesis of intermediate in fine chemicals including pharmaceuticals and agricultural chemicals, and a synthesis of a variety of polymer materials having optical properties.COPYRIGHT KIPO 2015

(Figure Presented). A new protocol for the direct cobaltcatalyzed alkylation of aryl halides has been developed that proceeds smoothly in the presence of phosphanes or bipyridines as ligands with a variety of alkyl halides, including challenging alkyl electrophiles bearing β hydrogen atoms (see scheme). Sensitive functional groups are tolerated on both coupling partners, thus, significantly extending the general scope of transition-metal-catalyzed alkylation of aryl halides.
