Nickel and Palladium Complexes of Ferrocene-Backbone Bisphosphine-Borane and Trisphosphine Ligands

Abstract

Reaction of a ferrocene-backbone bisphosphine-borane ligand, [Fe(η5-C5H4PPh2)(η5-C5H4P t Bu{C6H4(BPh2)-o})] (FcPPB), with [Ni(cod)2] (cod = 1,5-cyclooctadiene) or 0.5 equiv of [Pd2(dba)3] (dba = trans,trans-dibenzylideneacetone) afforded [Ni(FcPPB)] (1) and [Pd(FcPPB)] (2), respectively; compound 1 does not react with dba. The FcPPB ligand in complexes 1 and 2 is coordinated via both phosphine donors and an η3 BCC-interaction with boron …
