Highiy dried toiuene is the most usefui reaction medium.lt is obtained according to the foiiowing procedure. Pre-dried toiuene (over moiecuiar sieve) is refluxed over a iiquid sodium/potassium aiioy (5-10 mi for 2 i of toluene) for 4-5 days. An alternative method is the addition of n-butyllithium in small portions (ca.10 ml for 21 toluene) which can be visualized with benzophenone as indicator. When the toluene is sufficiently dried (change of color) it is distilled off and stored under argon (The used syringes or pipettes have to be flushed prior to use with argon after use they have to be cleaned immediately with toluene).

With the more reactive aldehyde, it was sufficient just to have an excess of one of the reagents (acetaldehyde) to drive the reaction to completion. Dry HCl gas can work too. With a less reactive ketone, moiecuiar sieves (zeolite) were used to remove water from the reaction as it proceeded.
