A triarylborane compound had been synthesized previously, and the metalation of this ligand with Au and Cu was studied before. Herein, a triarylborane/bis(phosphine) PBP sliver complex (PBPhP)AgCl was synthesized. The central boron behaved differently to different halogens. By treating AgF with PBPhP ligand, a ((PBPh,FP)Ag)2 dimer formed with no silver boron interaction, where boron bonded with fluoride to form borate. After treating with chlorotrimethylsilane/bromotrimethylsilane, (PBPhP)AgCl/(PBPhP)AgBr formed via halogen exchange, where boron bonded with silver as borane ligand. Both ((PBPh,FP)Ag)2 and AgPBPhPCl were charactered by NMR spectroscopy spectroscopically, and X-ray Diffraction crystal graphically, which indicate the structure change.
