The 1‐aryl‐2,1,3‐diazaboroles ArB(NCH 2 PPh 2 ) 2 C 6 H 4 (Ar = C 6 H 5 1a , 4‐MeC 6 H 4 1b , 4‐FC 6 H 4 1c ) result from the reactions of ArBCl 2 with 1,2‐(NHCH 2 PPh 2 ) 2 C 6 H 4 in the presence of triethylamine. The reactions of these new proligands in addition to the parent diazaborole HB(NCH 2 PPh 2 ) 2 C 6 H 4 ( 4 ) with a range of metal precursors [Ru 2 (µ‐Cl) 2 Cl 2 (η 6 ‐1,3,5‐Me 3 C 6 H 3 ) 2 ], [M 2 (µ‐Cl) 2 Cl 2 (η 5 ‐C 5 Me 5 ) 2 ], [M 2 (µ‐Cl) 2 (η 4 ‐C 8 H 12 ) 2 ] (M = Rh, Ir) and [AuCl(SC 4 H 8 )] 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.
