23. Purification of compounds containing the alkylidene malonate unit, such as 7 and 8, required incorporation of acetic acid (1 vol %) in the eluant. Since it was often difficult to completely remove the acetic acid in vacuo, we preferred to perform the metathesis reactions on material that did not require this additive for purification.
