A rapid, mild procedure is described for the synthesis of picolinyl esters of branched-chain, cyclic and unsaturated fatty acids, dicarboxylic acids and hydroxy acids by the reaction of the derived acid chloride with 3-pyridylcarbinol. The mass spectra of these derivatives contained abundant diagnos

The electron impact (EI) mass spectral analysis of the picolinyl esters of nine positional isomers of conjugated diacetylenic fatty acids showed prominent M + and [M-l] + peaks. In all cases there was a regular series of ions 14 amu apart in the high molecular weight range until the triple bond syst
