Transmetalation is a key method for the construction of element-element bonds. Here, we disclose the reactivity of [NiII(Ar)(I)(diphosphine)] compounds with arylgold(i) transmetalating agents, which is directly relevant to cross-coupling catalysis. Both aryl-for-iodide and unexpected aryl-for-aryl transmetalation are witnessed. Despite the strong driving force expected for Au-I bond formation, aryl scrambling can occur during transmetalation and may complicate the outcomes of attempted catalytic cross-coupling reactions.

We disclose unprecedented synergistic bimetallic Ni/Ag and Ni/Cu catalysts for regioselective γ,δ-diarylation of unactivated alkenes in simple ketimines with aryl halides and arylzinc reagents. The bimetallic synergy, which generates cationic Ni(II) speci

The compounds (η2-diarsane)bis(phenyl)platinum(II) with either a CH3, (CH3)2CH, (CH3)3C, F, Br, CF3, (CH3)3Si in the 4-position of the platinum-bound phenyl rings have been synthesized and studied photochemically.After excitation into the longest wavelength absorption band they eliminate the two substituted, platinum-bound rings as a biphenyl, but are photo-stable when excited by shorter wavelength UV-radiation.The elimination is exclusively intramolecular and stereospecific; it is an example of a concerted pericyclic at a transition metal.
