Hexane (ˈhɛkseɪn) is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C6H14. It is a colorless liquid, odorless when pure, and with boiling points approximately . It is widely used as a cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvent, and modern gasoline blends contain about 3% hexane. The term hexanes refers to a mixture, composed largely (>60%) of hexane, with varying amounts of the isomeric compounds 2-methylpentane and 3-methylpentane, and, possibly, smaller amounts of nonisomeric C5, C6, and C7 (cyclo)alkanes. These hexanes are cheaper than pure hexane and are often used in large-scale operations not requiring a single isomer (e.g., as cleaning solvent or for chromatography). Isomers C6H14 Uses In industry, hexanes are used in the formulation of glues for shoes, leather products, and roofing. They are also used to extract cooking oils (such as canola oil or soy oil) from seed

Synthesis of bicyclo[3.1.0]hexanes by (3+2) annulation of cyclopropenes with aminocyclopropanes

Alec Gagnebin, Bastian Antoine Rodolphe Claude Muriel, Jérôme Waser

We report the convergent synthesis of bicyclo[3.1.0]hexanes possessing an all-carbon quaternary center via a (3 + 2) annulation of cyclopropenes with cyclopropylanilines. Using an organic or an iridium photoredox catalyst and blue LED irradiation, good yields were obtained for a broad range of cyclopropene and cyclopropylaniline derivatives. The reaction was highly diastereoselective when using difluorocyclopropenes together with a removable substituent on the cyclopropylaniline, giving access to important building blocks for medicinal chemistry. With efficient methods existing for the synthesis of both reaction partners, our method grants a fast access to highly valuable bicyclic scaffolds with three contiguous stereocenters.

Gas separations in metal-organic frameworks

Miguel Gonzalez, Wendy Lee Queen

Owing to their high surface areas, tunable pore dimensions, and adjustable surface functionality, metal-org. frameworks (MOFs) can offer advantages for a variety of gas storage and gas sepn. applications. In an effort to help curb greenhouse gas emissions from power plants, we are developing new MOFs for use as solid adsorbents in post- and pre-combustion CO2 capture, and for the sepn. of O2 from air, as required for oxy-fuel combustion. In particular, MOFs with open metal cation sites or alkylamine-functionalized surfaces are demonstrated to provide high selectivities and working capacities for the adsorption of CO2 over N2 under dry flue gas conditions. Breakthrough measurements further show compds. of the latter type to be effective in the presence of water, while calorimetry data reveal a low regeneration energy compared to aq. amine solns. MOFs with open metal cation sites, such as Mg2(dobdc) (dobdc4- = 2, 5-dioxido-1,4-benzenedicarboxylate), are highly effective in the removal of CO2 under conditions relevant to H2 prodn., including in the presence of CH4 impurities. Redox-active Fe2+ sites in the isostructural compd. Fe2(dobdc) allow the selective adsorption of O2 over N2 via an electron transfer mechanism. The same material is demonstrated to be effective at 45 ° C for the fractionation of mixts. of C1 and C2 hydrocarbons, and for the high-purity sepn. of ethylene/ethane, propylene/propane, and CO/H2 mixts. Finally, it will be shown that certain structural features possible within MOFs, but not in zeolites, can enable the fractionation of hexane isomers according to the degree of branching or octane no.
