Monosulfate isomers

The rhodium-catalyzed conjugation reaction also proceeded well in the presence of ionic liquids [30] or in aqueous biphasic solutions using a water-soluble Rh(TPPMS) (TPPMS = triphenylphosphine monosulfate) catalyst and the surfactant sodium dodecyl sulfate (SDS) [31]. In this manner, all diene and triene components of sunflower, peanut, sesame, soybean, linseed, and rapeseed oil were converted to form 82-100% of conjugated products. Absolutely no nonconju-gated isomers remained.
