Reactivity of Mononuclear Rhodium(II) Compounds

Abstract: Mononuclear rhodium(II) compounds reported in the literature are tabulated, classified according to functionality and placed in one of four stability categories. The reactions reported for mononuclear Rh(II) compounds are presented and grouped according to reactivity type: adduct formation, ligand dissociation and substitution, dimerization, disproportionation, oxidation and reduction. Observed reactivity is rationalized on the basis of the factors that influence stability. Ligands that are sufficiently bulky can protect the metal from external attack by all but the smallest reagent molecules. Polydentate ligands can protect the metal from external attack or can impose coordination environments that destabilize Rh(I) or Rh(III). Electronic features of ligands that withdraw electron density or delocalize the unpaired electron from the metal promote stability. Reactivity can also depend on whether the Rh(II) complex is four coordinate (15 electron), five coordinate (17 electron) or six coordinate (19 electron). Because conventional two-electron oxidative addition and reductive elimination processes are not possible for Rh(II), redox behavior is of special interest. Mechanisms proposed for unusual oxidation and CH activation behavior in some Rh(II) systems are presented. Factors giving rise to differences in reactivity between different classes of Rh(II) compounds are evaluated.

Spatial competition with interacting agents

Abstract: Using agent-based modeling, we generalize Hotelling?s model of spatial competition with more than two firms in a two-dimensional space. Firms choose both price and location to maximize profits. The principle of minimum differentiation does not hold in general. Local duopolies emerge from the interaction betweenfirms. Firms do not spread uniformly across the two-dimensional space, nor do they all charge the same price. Firms in more competitive locations charge lower prices and generate less profit.

Fairness and freedom: A history of two open societies, New Zealand and the United States (1st ed.). David Hackett Fischer, Oxford University Press, 2012. 656 pp.

Abstract: The differences between histories, policies, and rhetorics of fairness and those of freedom might seem slight at first blush. In this book, David Hackett Fischer provides an in-depth history of the...

Bryophytes of Loud Thunder Forest Preserve, with an Updated Checklist of the Bryoflora of Rock Island County, Illinois

Abstract: An inventory of the bryophytes of Loud Thunder Forest Preserve (Rock Island, IL) was conducted in order to improve the knowledge of the bryoflora of the county. In total, 38 species were identified, adding 19 new taxa to the county checklist (53 mosses and 9 liverworts). Most of the existing collections of the bryoflora in the area were made more than a century ago, and since the new additions are common species this suggests that moss and liverwort diversity in Rock Island County is still underexplored.
