The mercaptals obtained by the acid catalyzed reaction of J3-ketoesters, e.g., ethyl acetoacetate, with methyl thioglycolate (73) undergo the Dieckmann cyclization with alcoholic potassium hydroxide at lower temperatures to give ethyl 3-hydroxy-5-methyl-2-thiophenecarboxylate (74) in 75% yield. ° Besides ethyl acetoacetate, ethyl a-ethylacetoacetate, ethyl benzoyl acetate, and ethyl cyclopentanonecarboxylate were also used in this reaction/ It is claimed that /8-diketones, hydroxy- or alkoxy-methyleneketones, or /8-ketoaldehyde acetals also can be used in this reaction. From acetylacetone and thioglycolic acid, 3,5-dimethyl-2-thiophenecarboxyl-ic acid is obtained. ... 

Various thiourea ligands have been used in the synthesis of mixed ligand complexes. A series of complexes [NiQ2L2] (HQ = ethylacetoacetate, L = thiourea, allyl-, benzoyl-, methyl-, diphenyl-thiourea) have been prepared. The complexes are all paramagnetic (/i = 3.02-3.27/iB) and have been assigned tra 5-octahedral structures.1014... 

None of the products formed in the reactions described above is considered to significantly change the reaction rates and product distributions by acting as a catalyst. However, Siskin et al. [106] reported that in the hydrolysis of methyl 1-naphthoate at 343 °C naphthalene was predominantly formed because the potential for autocatalysis arises. They concluded that decarboxylation of naphthoic acid, the main product at a lower temperature of 250 °C, led to the formation of naphthalene at 343 °C the reaction is catalyzed by the generated carbonic acid. In the hydrolysis of typical p-keto esters, ethylacetoacetate was completely converted to acetone, eAanol, and CO2 within 30 min at 250 °C. Under the same conditions, r-butyl acetate degraded into a bright red, insoluble mixture of unidentifled products resulting from polymerization of isobutylene [107]. 

It may be prepared by the eondensation of one mole each of phenyl-hydrazine and the lactim-form of ethylacetoacetate when 1-phenyl-3-methyl-pyrazolone is obtained by the elimination of a mole each of water and ethanol. The resulting product is subjected to methylation either with methyl iodide or dimethyl sulphate to yield phenazone.

From the experimental results obtained three liquid-liquid systems have been selected to be included here aniline/water, ethylacetate/water and ethylacetoacetate/water. The selected surfactants are SDS (sodium dodecyl sulphate), which is anionic, DTAB (dodecyl tri-methyl ammonium bromide), which is cationic, and Atlas G1300 (polyoxyethylene triglyceride ester) which is non-ionic.
