Technical Note: Reactivity of C1 and C2 organohalogens formation – from plant litter to bacteria [PDF]
Biogeosciences, 2012 C1/C2 organohalogens (organohalogens with one or two carbon atoms) can have significant environmental toxicity and ecological impact, such as carcinogenesis, ozone depletion and global warming.

Intramolecular halogen–halogen bonds?
Physical Chemistry Chemical Physics, 2013 By analysing the properties of the electron density in the structurally simple perhalogenated ethanes, X3C-CY3 (X, Y = F, Cl), a previously overlooked non-covalent attraction between halogens attached to opposite carbon atoms is found. Quantum chemical calculations extrapolated towards the full solution of the Schrödinger equation reveal the complex ...

Chemical, Electronic, and Electrical Properties of Alkylated Ge(111) Surfaces [PDF]
, 2010 The use of Ge in semiconductor electronics has been constrained by the lack of a simple method of passivating the crystal surface. Toward that end, we have explored the utility of chemically bonded hydrocarbon monolayers.

Halogenation as a Strategy to Improve Antiplasmodial Activity: A Report of New 3-Alkylpyridine Marine Alkaloid Analogs [PDF]
International Journal of Travel Medicine and Global Health, 2019 Introduction: Due to the emergence of resistance to antimalarial drugs as well as the lack of vaccination for malaria, there is an urgent demand for the development of new antimalarial alternatives.

Selective C(sp2)−H Halogenation of "click" 4-Aryl-1,2,3-triazoles [PDF]
, 2017 Selective bromination reactions of “click compounds” are described. Electron-neutral and electron-deficient arenes selectively undergo unprecedented Pd-catalyzed C–H ortho-halogenations assisted by simple triazoles as modular directing groups, whereas ...

Enzymatic functionalization of carbon-hydrogen bonds [PDF]
, 2011 The development of new catalytic methods to functionalize carbon–hydrogen (C–H) bonds continues to progress at a rapid pace due to the significant economic and environmental benefits of these transformations over traditional synthetic methods.

Halogen⋯halogen contra C–H⋯halogen interactions
CrystEngComm, 2014 Pressure affects the competition between C–H⋯X hydrogen bonds and X⋯X halogen⋯halogen interactions. In bromomethane, CH3Br, pressure changes the molecular arrangement of the two solid-state phases of this compound: low-pressure phase α is dominated by halogen⋯halogen interactions, whereas above 1.5 GPa the β phase is governed by C–H⋯halogen bonds.
