We report on (i) the reactivity of the title compound trans-[Cl(PMe(3))(2)Pt{μ-BN(SiMe(3))(2)C=C}Ph] (1), which underwent a photochemical rearrangement reaction to afford the platinum boryl complex trans-[Cl(PMe(3))(2)PtBN(SiMe(3))(2)C≡CPh] (2), (ii) a ring-opening reaction by chemoselective boron-carbon bond cleavage resulting in the amino(vinyl)borane trans-[Cl(PMe(3))(2)PtCH=C(BClN(SiMe(3))(2))Ph] (3), and (iii) a Cl-Br ligand exchange on the platinum atom yielding the Br-derivate trans-[Br(PMe(3))(2)Pt{μ-BN(SiMe(3))(2)C=C}Ph] (4). All compounds were fully characterized by multinuclear NMR spectroscopy and single crystal X-ray diffraction analysis.
