ester's Usage Examples:

Perkin, junr., in 1883, that ethylene and trimethylene bromides are capable of acting in such a way on sodium acetoacetic ester as to form triand tetramethylene rings.

Held synthesized the acid from ethyl chlor-acetoacetate (from chlorine and acetoacetic ester) by heating with potassium cyanide and saponifying the resulting nitrile.

The half nitrile of malonic acid is cyanacetic acid, CN CH 2 COOH, which, in the form of its ester, may be obtained by the action of a solution of potassium cyanide on monochloracetic acid.

Many esters of malonic acid have been prepared, the most important being the diethyl ester (malonic ester), CH 2 (000C 2 H 5) 2, which is obtained by dissolving monochloracetic acid in water, neutralizing the solution with potassium carbonate, and then adding potassium cyanide and warming the mixture until the reaction begins.

Curtius, Ber., 18 94, 2 7, p. 779; 1896, 29, p. 1166), N2H4�H20 HONO R�Cooh-R�COOR' -- R�CONH�NH 2 - > acid ester hydrazide C 2 H50H HCI R.

Knorr, by the action of ammonia on aceto-acetic ester, obtained (3-imidobutyric ester, which with nitrous acid yields a-isonitroso-(3-imidobutyric ester, CH 3 C(:NH) C(:N OH) CO 2 C 2 H 5.

It is a most important synthetic reagent; with sodium or sodium ethylate it forms sodio-malonic ester, which reacts readily with alkyl halides, forming alkyl malonic esters, which are again capable of forming sodium derivatives, that by further treatment with alkyl halides yield the di-alkyl malonic esters.

It is the methyl ester of a neutral body colchicein, which may be obtained in white acicular crystals.

Muller, Ann., 1864, 131, p. 35 2), and by the action of silver oxide on s-di-chloracrylic ester .at 125° C. (0.

Its ethyl ester condenses with hydrazine to form pyrazolone (R.
