Self condensation of ethyl acetate

WebWhen the sodium salt of ethyl aceto- acetate is treated with ethyl trifluoroacetate, no ethyl yyy-trifluoroacetoacetate is formed; instead high-boiling materials, presumably further condensation products, are isolated. The two /3-keto-esters are therefore not in equilibrium. WebFor example, even though ethyl benzoate has no alpha hydrogens, reducing the number of products, the possibility of self-condensation of ethyl …
