Carboxylic acid triethylamine salts yield mixed anhydrides which, when treated with ethoxymagnesiomalonic esters give the benzoylated malonate. Alternatively, treatment of the mixed anhydrides with sodium tetracarbonylferrate(II) produces the aldehyde derived from the parent aliphatic or aromatic carboxylic acid in good yield. ... 

Three methods for the conversion of 3-chlorocarbonyl-1,2,5-thiadiazole (81) to ketones were investigated by Gill. The Lund procedure for the malonic ester synthesis of ketones proved quite successful for the preparation of 3-acetyl-1,2,5-thiadiazole (83). Condensation of 81 with diethyl ethoxymagnesiomalonate provides the ketodiester (82) which undergoes acid hydrolysis and decarboxylation to 83 in 90 % yield. The same reaction sequence employing the sodio derivative of malonic ester was much less efficient.
