Abstract: | The Wittig reaction between alkylidene triphenylphosphoranes [R — CH = P(C6H5)3, where R varied from H to n — C17H35] and methyl 12-oxooctadecanoate or methyl 10-oxohexadecanoate in dimethylformamide (DMF) has been employed in the synthesis of a partial homologous series of esters of branched chain fatty acids in high yields. The effect of various ratios of reactants in both DMF and dimethylsulfoxide (DMSO) was investigated. Purification from triphenylphosphine oxide was readily accomplished by chromatography on a column of silicic acid-Celite impregnated with silver nitrate. |
