Bruson and Riener (1,2,3,4) have recently reported the cyanoethylation of ketones, cyanoesters, nitroparaffins, aldehydes, and two /S-keto esters with acrylonitrile in the presence of the basic condensing agents, potassium hydroxide, sodium methoxide, and benzyltrimethylammonium hydroxide (Triton B).In the present investigation the cyanoethylation of a number of ß-keto esters, /3-diketones, and methyl ketones has been studied in the presence of Triton B and benzyltrimethylammonium butoxide (BTAB) as the condensing agents.

The carbethoxylation of methyl ketones with diethyl carbonate to form /S-keto esters has been effected previously by means of sodium ethoxide (1), sodium triphenylmethide (2), or sodium amide (3); and the acylation of ketones SUMMARY Various ketones have been carbethoxylated with diethyl carbonate in the presence of lithium amide to give ß-keto esters in fair to good yields.Certain ketones have been acylated with aliphatic and aromatic esters to produce symmetrical ß-diketones in good yields.As previously observed with sodium amide (7), the acylation of methyl ethyl ! The lithium amide used in this investigation was purchased from the A.
