“…34 The yield of this oxidation was considerably lower with pyridinium dichromate (41% yield). A subsequent Wittig reaction with a dodecyl phosphonium bromide salt 35 and n-BuLi as a base furnished 6 as a mixture of stereoisomers. Rather than separating this complex mixture of compounds with very close R f values on silica gel, the salts were simply removed by filtration on a Celite plug and the mixture was used for the next step.…”

“…Surface active compounds. Two surface active compounds were investigated: dodecyl-di(/?-oxyethyl)-bcnzene ammonium chloride (DOBAC) [3] and dodecyl-triphenyl phosphonium bromide (DTPB) [1,4,5], The compounds were dissolved in ethanol. In a first series of experiments, bactericidal concentrations of both surface active compounds were evaluated.…”
