✦ Synopsis

The methyl esters of some mono-unsaturated fatty acids have been methylthiolated by the iodine-catalysed addition of dimethyl disulfide across the double bond. The resulting derivatives are suitable for gas chromatography. The fragmentation of the derivatives on electron impact yields mass spectra which allow immediate recognition of the position of the original double bond.
