Abstract

Reactions involving other alkali metals are not as numerous. The properties of colloidal alkali metals have been known for many years but they remain unexploited in synthesis due to the difficulties associated with their preparation. Luche and co-workers observed that small lumps of potassium could be dispersed in a few minutes by sonication in toluene or xylene at 10 °C in a cleaning bath [83]. The colloid generated was used in a number of reactions; for instance, a Dieckman cyclization could be effected within 5 min (Scheme 40).
