The synthesis of racemic 4-ethyl fatty acids is reported. A Grignard reagent was first prepared by 3-chloroalkane reacting with magnesium and then 4-ethyl fatty acid methyl esters were synthesised by coupling the Grignard reagent with methyl 3-bromopropionate in the presence of the catalyst Li 2CuCl4. 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, 4-ethylheptanoic acid, 4-ethyloctanoic acid, 4-ethylnonaoic acid and 4-ethyl decanoic acid are described. The structures of the 4-ethyl fatty acid methyl esters and 4-ethyl fatty acids were confirmed by 1H NMR, 13C NMR and HRMS.

Solid state reactions of acids RCOOH (R = n-C7H15, BuC(Et)H, n-C9H19, PhCH2, PhCH 2CH2, H2C=CH(CH2)8, or MeOOC(CH2)3) with Pb(OAc)4 combined with KCl, NaCl, CdCl2, or NH4Cl in the absence of a solvent and without mechanical activation afford chlorohydrocarbons RCl. The corresponding reactions of acids HOOC(CH2)nCOOH (n = 3-6) give dichloroalkanes Cl(CH2)nCl and γ-butyrolactone (n = 3).
Symmetric and asymmetric proton transfer from heptane and octane radical cations to heptane molecules in γ-irradiated n-C7H16-n-C8H18-2-C6H 13CL crystals: Structural disorder in mixed alkan

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 impor
