Zeng, Jing published the artcileSelective Co/Ti Cooperatively Catalyzed Biaryl Couplings of Aryl Halides with Aryl Metal Reagents, HPLC of Formula: 6313-54-8, the publication is Organic Letters (2013), 15(20), 5342-5345, database is CAplus and MEDLINE.
Various aryl bromides or chlorides, including those bearing a free COOH, OH, CONHR, and SO2NHR group, coupled with aryl magnesium or lithium reagents in the presence of 7.5 mol% CoCl2/15 mol% PBu3 and substoichiometric Ti(OEt)4 (40 mol% to ArM) at room temperature in high yields with high chemo- and regioselectivity. This simple reaction represents the first example of Co/Ti cooperative catalysis which plays a key role in suppressing undesired homocouplings.
