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
