Effects of solvent and structure on the reactivity of 6-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents [PDF]
Journal of the Serbian Chemical Society, 2009 The rate constants for the reactions of diazodiphenylmethane (DDM) with 6-substituted nicotinic acids in aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, together with literature data for benzoic and

2-(Carboxymethylsulfanyl)pyridine-3-carboxylic acid monohydrate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°.

Reaction of Pyridine Bases with Carboxylic Acids in Benzene [PDF]
Bulletin of the Chemical Society of Japan, 1977 Abstract The reaction of pyridine bases with aliphatic monocarboxylic acids has been studied by means of the partition method. Partition was carried out at 25 °C between benzene and 0.10 mol dm−3 (Na, H) ClO4 aqueous solution, the total concentration of pyridine base and that of carboxylic acid being less than 2×10−2 mol dm−3 and 1.0 mol
