Abstract
Coordination of a bulky pyridinyl-phosphine (P˜N) ligand toward CuBr was investigated. However, this P˜N donor behaves as a monodentate via the coordination of phosphine to form a bromide bridged dimeric [(P˜N)Cu(μ-Br)2Cu(P˜N)], which was characterized by spectral and crystal structural analysis. It appeared that the “PCu(μ-Br)2CuP” unit is planar with a short distance between Cu…Cu' [2.7585(9) Å]. The catalytic activity on Sonogashira coupling of phenylacetylene with aryl halides was studied.
