Cooperative Nitrile Coordination Using Nickel and a Boron‐Containing Secondary Coordination Sphere. Issue 17 (15th February 2023) - Clapson, Marissa L.
Abstract: Metal‐ligand cooperation has emerged as a versatile tool for substrate activation in chemical reactivity. Herein, we provide the synthesis and characterization of a monoboranyl‐containing analogue of the ubiquitous bulky diphosphine ligand, 1, 2‐ bis (di‐ tert ‐butylphosphino)ethane, whose reactivity has been examined using nickel. Together, the pairing of nickel and boron provides a platform that allows for the cooperative coordination of organonitriles, giving unusual examples of intermolecularly bound dinickelacycles. Abstract : Collaborative work : The synthesis of a new monoboranyl ligand scaffold is described. This ambiphilic diphosphine allows for the cooperative coordination of organonitriles in partnership with nickel(0).
