Malonates in Cyclocondensation Reactions [PDF]
Molecules, 2001 The use of malonates such as diethyl malonates 9, (chlorocarbonyl)ketenes 15 and bis(2,4,6-trichlorophenyl) malonates 18 as reagents for cyclocondensation with 1,3-dinucleophiles to give six-membered heterocycles is described. Further attempts to use malonates such as bis(trimethylsilyl) malonates 19 and bis(carbamimidoyl) malonates 29 as new ...

Brain and Development, 1994
Three infants with malonic aciduria are reported, one of whom could be studied in detail. All children had severe and progressive encephalopathy with intermittent ketoacidosis and hypoglycemia. One infant died of cardiomyopathy. Biochemical studies revealed that one patient had neither malonyl-CoA decarboxylase nor glutaryl-CoA dehydrogenase ...

Malonate and Plant Respiration
Nature, 1947Since Quastel and Whetham's discovery in 19251, biochemists have come to regard the malonate ion as one of the very few specific enzyme inhibitors—as a competitive inhibitor of succinic dehydrogenase2 Malonate has therefore been widely used with animal tissue, in work designed to elucidate the Krebs cycle.

Decomposition of Malonic Anhydrides
Journal of the American Chemical Society, 2012Malonic anhydrides decompose at or below room temperature, to form a ketene and carbon dioxide. Rate constants for the thermal decomposition of malonic, methylmalonic, and dimethylmalonic anhydrides were measured by NMR spectroscopy at various temperatures, and activation parameters were evaluated from the temperature dependence of the rate constants ...

Malonic aciduria and cardiomyopathy
Journal of Inherited Metabolic Disease, 1993Malonyl-CoA decarboxylase (EC 4.1.1.9) deficiency (McKusick 248360) with malonic aciduria was first reported by Brown et al (1984) in a patient with short stature, repeated episodes of vomiting and mild developmental delay. A second patient with malonic aciduria and malonyl-CoA decarboxylase deficiency was reported by Haan et al (1986).

Measurements of Oxalic Acid, Oxalates, Malonic Acid, and Malonates in Atmospheric Particulates
Environmental Science & Technology, 2008This study systematically examined effects of analytical approaches on resultant concentrations of oxalic acid, oxalates, malonic acid, and malonates. Results demonstrated that employing separate water extraction and THF extraction is required to properly quantify dicarboxylic acids vs dicarboxylates using IC or GC-MS.

Analysis of the content and distribution of organic acids in chickpea plants (Cicer arietinum L.) showed that malonate was the most abundant acid in roots and nodules, whereas malate was the main acid in leaves and stems. The highest concentration of malonate in roots was in the apices.

Hydration and ion pairing of maleinates, malonates, and substituted malonates in aqueous solution
Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1976Association constants and enthalpies of association for salts of maleic acid, malonic acid and substituted malonic acids with alkali metals and alkaline earth metals were measured colorimetrically in aqueous solution. Agreement with previous determinations by other methods was obtained.
