Synthesis and C−C Coupling Reactivity of a Dinuclear NiI−NiI Complex Supported by a Terphenyl Diphosphine

摘要

Reactions involving multielectron transfers between metal centersnand substrates are at the core of many important transformationsnin biology and chemistry.n1,2nWhile biological redox reactions arencommonly performed by multimetallic enzyme active sites, thenmajority of synthetic homogeneous catalysts are monometallic,ndespite significant advances in cluster chemistry over the last fewndecades.n2,3nFor example, group 10 monometallic complexes havenbeen used for a wide variety of catalytic organometallic transforma-ntions involving redox cycling, whereas bimetallic complexes havenfound fewer applications in catalysis. This may be due to the usenof multidentate ligands, which hinder reactivity by saturating thenmetal coordination sphere.
