Other reactions involving the addition of carbanions are reactions like Perkin s reaction, Claisen condensation, benzilic acid rearrangement and Michael addition. 

The other variables may be altered to the same wide extent as in the route based on the Claisen condensation. The rearrangement also occurs under the influence of other basic catalysts, including sodium metal, sodium hydride and sodium hydroxide, and indeed it has been suggested that these strongly basic species are more effective than potassium carbonate. For instance, the diacetyl derivative of 2,4-dihydroxyacetophenone did not rearrange in the presence of potassium carbonate (33JCS1381) but did so on treatment with sodium in benzene <49PIA(A)(30)57).
