Abstract:
We report the convenient synthesis of Ni(DQ)2 (DQ = duroquinone) from readily available Ni(II) and Ni(0) precursors, guided by DFT calculations. By virtue of its π-accepting homoleptic ligand environment, Ni(DQ)2 undergoes facile ligand exchange with phosphine, bis-nitrogen, and diene ligands and thus represents a convenient Ni(0) source in synthetic organometallic chemistry. As a precatalyst, Ni(DQ)2 is found be a competent air-stable precursor for emerging methodology where Ni(COD)(DQ) is ineffective (COD = 1,5-cyclooctadiene).

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
