Abstract

The reaction between 2-chlorobenzylamine or 2-chlorobenzylalcohol and Pd(ItBu)2 (ItBu = 1,3-di-tert-butylimidazol-2-ylidene) in benzene affords the dimeric complexes [Pd(ItBu)(μ-NH{2-CH2C6H4})]2 and [Pd(ItBu)(μ-O{2-CH2C6H4})]2; the latter has been structurally characterised. The syntheses, structural characterisation and reactivity of the Pd-NHC amine complexes [(ItBu)Pd(R-4-C6H4)(morpholine)Cl] (R = Me, OMe, CO2Me), intermediates in the Buchwald–Hartwig aryl amination reaction, are also reported.
