acids is reported. A Grignardreagent was first prepared by 3-chloroalkane reacting with magnesium and then 4-ethyl fatty acid methyl esters were synthesised by coupling the Grignardreagent with methyl 3-bromopropionate in the presence of the catalyst Li2CuCl4. The 4-ethyl fatty acid methyl esters were saponified and then acidified to give the 4-ethyl fatty acids. The syntheses of 4-ethylhexanoic acid

A study has been made of the isomeric composition of secondary chloroheptanes formed upon γ-irradiation at 77 K and subsequent melting of heptane containing 1 mol% 2-chlorohexane and various concentrations of octane. It is observed that the relative importance of 2-chloroheptane increases as a result of the presence of octane in the crystallites. This increase is attributed to selective proton transfer from ground state heptane radical cations to penultimate CâH bonds in heptane molecules. The proton transfer is induced by (partial) dislocation of heptane molecules adjacent to octane solute molecules, which brings the penultimate heptane CâH bonds into close contact with planar chain-end CâH bonds in heptane radical cations. Proton transfer from extended all-trans octane radical cations (on which the positive hole temporarily resides) to heptane molecules may also contribute to the observed effect. The results have important implications with respect to the molecular packing in binary n-alkane crystals. In binary n-alkane crystals, in which the shorter component is predominant, molecules of the longer component cannot be fully accommodated in one molecular layer of the crystal, even with a chain length mismatch of only one methylene unit; instead (at least partial) dislocation of adjacent molecules of the shorter component takes place. Such dislocations do not extend indefinitely over the crystal, however, and crystal order is restored by squeezing, deformation and changes in conformation of the appropriate molecules, including molecules of the shorter component.

The present invention is directed to provide an efficient production method which is capable of not only obtaining a cyclic sulfonic acid ester (sultone) at low cost and in high yield, but also the sulfonic acid ester (sultone) stably even in a commercial scale. The present invention relates to a method for producing hydroxysultone comprising a first step where a diol having a specified structure and a thionyl halide are reacted to obtain a cyclic sulfite having a specified structure, and a second step where the cyclic sulfite is reacted with water or/and alcohol; a method for producing an unsaturated sultone having a specified structure comprising a third step where a hydroxylsultone having a specified structure is reacted with an acid halide or an acid anhydride to obtain an intermediate, subsequently the intermediate is treated with a base; as well as a cyclic sulfite having a specified structure.

In this article, we report a general protocol for the direct decarboxylative chlorination, iodination, and bromination of aliphatic carboxylic acids catalyzed by ironsalts under visible light. This method enjoys a broad substrate scope with good functional group compatibility, including complex natural products. Benzylic and allylic C(sp3)–H bonds can be retained under the oxidative halogenation conditions
