Transformations that selectively functionalize aliphatic C-H bonds hold significant promise to streamline complex molecule synthesis. Despite the potential for site-selective C-H functionalization, few intermolecular processes of preparative value exist. Herein, we report an approach to unactivated, aliphatic C-H bromination using readily available N-bromoamide reagents and visible light. These halogenations proceed in useful chemical yields, with substrate as the limiting reagent. The site selectivities of these radical-mediated C-H functionalizations are comparable (or superior) to the most selective intermolecular C-H functionalizations known. With the broad utility of alkyl bromides as synthetic intermediates, this convenient approach will find general use in chemical synthesis.

The liquid crystalline properties of the homologous series of 2-(trans-4-n-alkylcyclohexyl)propane-1,3-diols 1 is described.These compounds exhibit thermotropic and after addition of small amounts of water also lyotropic liquid crystalline properties.The phase behaviour is described and explained by a general model, whereby hydrogen-bonding and hydrophobic interactions are considered.
