ylide was consumed between successive additions. When no color change was observed upon addition of the base the reaction mixture was diluted with an equal volume of water. The mixture was extracted with diethyl ether three times, the combined organic layers were washed with water several times, dried over anhydrous magnesium sulfate and the solvent distilled. The pure all-trans isomer was obtained by heating the olefins inp-xylene with a catalytic amount of iodine. The pure product was obtained after repeated crystallization from THFimethanol.
