This article seeks to outline and explore some of the conditions necessary for International Organizations (IOs) to perform in a public interest fashion through a case study of the Principles of corporate governance formulated by the OECD. Rather than the more commonly documented pathological and dysfunctional behavioural forms of IOs, the case of the Principles, both in their formulation by the OECD, and in their assessment by the World Bank through the ROSC process, represent an episode of IO agency protecting and promoting a wider public interest. In exercising their agency, IO staff, have made the Principles more agreeable to a wider range of interested parties, giving them a general interest orientation, in accordance with a proceduralist definition of public interest. This case should therefore encourage IPE scholars to consider carefully and systematically the sets of circumstances and conditions, which might be required for IO agency to take more socially useful forms. In the final section, three indicators are identified which might be evaluated in future research into the positive public interest agency of IOs across a range of cases.

Drawing on the literature in criminology and media studies on the nature of social understandings of corporate crime and its representation in the media, this paper takes one small but important step in this direction by carrying out a linguistic case study on the news coverage of one sequence of events which resulted from corporate negligence – the Paddington rail crash, a sequence of news events that were important as they led to legal change as regards corporate responsibility in Britain. The paper concludes by showing that while the news coverage played an important part in leading to a change in the law regarding corporate responsibility, although this received little coverage in the press.

A series of bis(oxazoline) metal(II) complexes has been supported on silica and carbon supports by non-covalent immobilisation using an ionic liquid. The catalytic performance of these solids was compared for the enantioselective Diels-Alder reaction between N-acryloyloxazolidinone and cyclopentadiene and the Mukaiyama-aldol reaction between methyl pyruvate and 1-methoxy-1-trimethylsilyloxy-propene. In both reactions the enantioselectivity was strongly influenced by the choice of support displaying enantioselectivies (ee values) up to 40% higher than those conducted under homogeneous reaction conditions.

The title compound is readily prepared from 5'-O-monomethoxytrityl-3'-thiothymidine (5); cleavage of the P–S bond can be accomplished by mild oxidative hydrolysis.

New air-stable ruthenium(II) complexes that contain the aryldiamine ligand [C6H3(CH2-NMe2)(2)-2,6](-) (NCN) are described. These complexes are [RuCl{eta(2)-C,N-C6H3(CH2NMe2)(2)-2,6}(eta(6)-C10H14)] (2; C10H14 = p-cymene = C6H4Me-Pr-i-4), [Ru{eta(2)-C,N-C6H3(CH2NMe2)(2)-2,6}(eta(5)-C5H5)(PPh3)] (5), and their isomeric forms [RuCl{eta(2)-C,N-C6H3(CH2NMe2)(2)-2,4}(eta(6)-C10H14)] (3) and [Ru{eta(2)-C,N-C6H3(CH2NMe2)(2)-2,4}(eta(5)-C5H5)(PPh3)] (6), respectively. Complex 2 has been prepared from the reaction of [Li(NCN)](2) with [RuCl2(eta(6)-C10H14)](2), whereas complex 5 has been prepared by the treatment of [RuCl{eta(3)-N,C,N-C6H3(CH2NMe2)(2)-2,6}(PPh3)] (4) with [Na(C5H5)](n). Both 2 and 5 are formally 18-electron ruthenium(II) complexes in which the monoanionic potentially tridentate coordinating ligand NCN is eta(2)-C,N-bonded, In solution (halocarbon solvent at room temperature or in aromatic solvents at elevated temperature), the intramolecular rearrangements of 2 and 5 afford complexes 3 and 6, respectively. This is a result of a shift of the metal-C-aryl bond from position-1 to position-3 on the aromatic ring of the NCN ligand. The mechanism of the isomerization is proposed to involve a sequence of intramolecular oxidative addition and reductive elimination reactions of both aromatic and aliphatic C-H bonds. This is based on results from deuterium labeling, spectroscopic studies, and some kinetic experiments. The mechanism is proposed to contain fully reversible steps in the case of 5, but a nonreversible step involving oxidative addition of a methyl NCH2-H bond in the case of 2. The solid-state structures of complexes 2, 3, 5, and 6 have been determined by single-crystal X-ray diffraction. A new dinuclear 1,4-phenylene-bridged bisruthenium(II) complex, [1,4-{RuCl(eta(6)-C10H14)}(2){C-6(CH2NMe2)(4)-2,3,5,6-C,N,C',N'}] (9) has also been prepared from the dianionic ligand [C-6(CH2NMe2)(4)-2,3,5,6](2-) (C2N4). The C2N4 ligand is in an eta(2)-C,N-eta(2)-C',N'-bis(bidentate) bonding mode. Compound 9 does not isomerize in solution (halocarbon solvent), presumably because of the absence of an accessible C-aryl-H bond. Complex 9 could not be isolated in an analytically pure form, probably because of its high sensitivity to air and very low solubility, which precludes recrystallization.

The disilylated compound 1,4-bis(trimethylsilyl)-2,3,5,6-tetrakis((dimethylamino)methyl)benzene, (Me(3)Si)(2)C2N4, 4, can be electrophilically palladated selectively at the C-Si bonds to afford the neutral 1,4-bis(palladium) complex [(AcOPd)(2)(C2N4)], from which the dicationic [(LPd)(2)(C2N4)](2+) (L = MeCN) organometallic species are accessible. The monosilylated species (Me(3)Si)(H)C2N4, 5, can be used for the preparation of the dicationic heterodinuclear platinum(II)-palladium(II) species [(LPd)(LPt)(C2N4)](2+) (L = MeCN) via a sequence of transmetalation of the organolithium derivative of 5 with [PtCl2(SEt(2))(2)], followed by a C-Si bond palladation reaction.

Companies in Victorian Britain operated in a laissez-faire legal environment from the perspective of outside investors, implying that such investors were not protected by the legal system. This article seeks to identify the alternative mechanisms that outside shareholders used to protect themselves by examining the dividend policy and governance of over 800 publicly traded companies at the beginning of the 1880s. We assess the importance of these mechanisms by estimating their impact on Tobin's Q. Our evidence suggests that dividends and well-structured and incentivized boards of directors may have played a role in protecting the interests of outside investors.
