The reaction of the pivalamidate-bridged platinum(III) dinuclear complex [Pt2(NH3)4(tBuCONH) 2(OH2)2]4+ with phenol in water gave 2-hydroxyphenyl platinum dinuclear complex [Pt2(NH3) 4(tBuCONH)2(C6H4(OH))] 3+ via ortho C-H bond activation in the axial position. The identical compound and the analogous phenyl complex [Pt2(NH3) 4(tBuCONH)2(C6H5)] 3+ could alternatively be synthesized from the reactions of [Pt 2(NH3)4(tBuCONH)2(OH 2)2]4+ with the corresponding arylboronic acids via transmetalation. The reactivities of the novel aryl-Pt2 compounds toward nucleophiles and the effect of UV light irradiation were investigated. The ESR spectra showed that the axial aryl-Pt bond is homolytically cleaved by UV-light irradiation to give the aryl radical and the Pt(III)-Pt(II) paramagnetic complex.
