Recent reports in Australia have suggested that some medical practitioners are refusing to treat children who have not been vaccinated, a practice that has been observed in the USA and parts of Europe for some years. This behaviour, if it is indeed occurring in Australia, has not been supported by the Australian Medical Association, although there is broad support for medical practitioners in general having the right to conscientious objection. This paper examines the ethical underpinnings of conscientious objection and whether the right to conscientious objection can be applied to the refusal to treat unvaccinated children. The implications of such a decision will also be discussed, to assess whether refusal to treat unvaccinated children is ethically justifiable. The best interests of both existing and new patients are crucially important in a doctor's practice, and the tension between these two groups of patients are contemplated in the arguments below. It is argued that on balance, the refusal to treat unvaccinated children constitutes unjustified discrimination.

The platinum(0) monocarbonyl complex, [(Cy(3)P)(2)Pt(CO)], was synthesized by reaction of [(Cy(3)P)(2)Pt] with [(η(5)-C(5)Me(5))Ir(CO)(2)] and subsequent irradiation. X-ray structure analysis was performed and represents the first structural evidence of a platinum(0) monocarbonyl complex bearing two free phosphine ligands. Its corresponding dicarbonyl complex [(Cy(3)P)(2)Pt(CO)(2)] was synthesized by treatment of [(Cy(3)P)(2)Pt] with CO at -40 °C and confirmed by X-ray structure analysis.

Herein we report for the first time full details on the synthesis and structural characterization of novel homodinuclear bridging cobalt and nickel borylene complexes containing bridging carbonyl ligands, an unusual coordination motif rarely before observed for homodinuclear borylene complexes. Furthermore, the homodinuclear nickel complex represents the first instance of a nickel borylene complex. Quantum chemical analyses of charge-density topology, electron localization function (ELF) and natural charges indicate the absence of direct metal-metal bonds in both the cobalt and nickel systems, in contradiction with electron counting. The topology of the Laplacian of the electron density and of the ELF around the bridging boron atom is consistent with a bis-metallo-substituted borane situation for the dicobalt system, but with a three-center-bonding borylene for the dinickel complex.

Herein we report on the synthesis and structural characterization of a representative range of novel heterodinuclear bridging rhodium and iridium borylene complexes. The iridium borylene complexes feature an unusual coordination mode of the borylene ligand. Furthermore, the first instance of a heterodinuclear-bridged borylene compound containing a chromium atom in the three-membered ring is reported.
