Effects of solvent and structure on the reactivity of 2-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents [PDF]
The rate constants for the reactions of diazodiphenylmethane (DDM) with 2-substituted nicotinic acids in nine aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, were correlated using the Kamlet-Taft

Kinetics and mechanism of the reaction of substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane in dimethylformamide [PDF]
Correlation of the data for the reaction of 11 substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) with calculated atomic charges on the carboxylic group showed that the reaction in this solvent may proceed via a concerted transition state.

Enthalpy-entropy compensation effect in chemical kinetics and experimental errors: a numerical simulation approach [PDF]
Many kinetic studies concerning homologous reaction series report the existence of an activation enthalpy-entropy linear correlation (compensation plot), its slope being the temperature at which all the members of the series have the same rate constant ...
