Abstract

The 1-aryl-2,1,3-diazaboroles ArB(NCH2PPh2)(2)C6H4 (Ar = C6H5 1a, 4-MeC6H4 1b, 4-FC6H4 1c) result from the reactions of ArBCl2 with 1,2-(NHCH2PPh2)(2)C6H4 in the presence of triethylamine. The reactions of these new proligands in addition to the parent diazaborole HB(NCH2PPh2)(2)C6H4 (4) with a range of metal precursors [Ru-2(mu-Cl)(2)Cl-2((6)-1,3,5-Me3C6H3)(2)], [M-2(mu-Cl)(2)Cl-2((5)-C5Me5)(2)], [M-2(mu-Cl)(2)((4)-C8H12)(2)] (M = Rh, Ir) and [AuCl(SC4H8)] have been explored. Rather than forming chelating, bidentate mono-metallic complexes, these ligands are found to support the formation of bimetallic complexes without any indication of B-C activation (oxidative addition, transmetallation etc.). In the presence of excess 1a-b, iridium is found to form ligand bridged coordination polymers.
