synthesis of [Pd(IPr*)(acac)Cl] has been developed from commercially available Pd(acac)2 and the easily prepared IPr*·HCl (acac = acetylacetonate; IPr* = N,N′-bis(2,6-bis(diphenylmethyl)-4-methylphenyl)imidazol-2-ylidene). The reactivity of the resulting complex [Pd(IPr*)(acac)Cl] (1) as a highly active PdII precatalyst for the Buchwald–Hartwig arylamination coupling has been explored. A wide range of substrates
