A highlyactivecobaltcatalyst system has been developed for the cross-coupling reactions of arylmagnesium reagents and aryl bromides. In the presence of 1 mol% CoCl2, 2 mol% IPr·HCl and 2 mol% NaO t Bu, a wide range of (hetero)biaryls are prepared in 51–99% yields at room temperature within a short reaction time.

Ni-catalyzed Suzuki cross-coupling reactions of aryl chlorides with arylboronicacids has been reported. The results show that under the optimized reaction conditions, the new catalytic system with a Ni(II) σ-arylcomplex as precatalyst and a diaminophosphine oxide as preligand tolerates a variety of functional groups and is efficient for both electron-rich and electron-deficient aryl chlorides, though

series of Pd(II)‐enaminone complexes, termed Pd(eao)2, have been synthesized and characterized. The investigation on the catalytic activities of these new Pd(II)‐reagents has proved that the Pd(eao)2‐1 possesses excellent catalytic activity for the Suzuki‐ Miyaura cross couplingreactions of aryl bromides/chlorides with aryl/vinyl boronic acids in the environmentally benign media of aqueous PEG400 at

CuO-catalyzed Suzuki–Miyaura cross-coupling reactions of arylboronicacids with aryl iodides and bromides using 2,2′-diamino-6,6′-dimethylbiphenyl as the ligand are described in the paper. Under suitable conditions, all reactions gave the desired coupling products in moderate to excellent yields.Graphical Abstract

well-defined N-heterocycliccarbene (NHC)-palladium chloride-imidazole complexesderived from IPrHCl or IMesHCl, PdCl2 and 1-methylimidazole exhibits high catalytic activity in the room-temperature Suzuki-Miyauracouplingreactions of aryl or heteroaryl chlorides. Moreover, the large-scale (20.0 mmol) couplings in the presence of 0.01 mol% catalyst loading can also give the corresponding coupling products
